I would like to give one of the reasons (Disclaimer: I am associated with Blockonomics).
There is no support of segwit change addresses yet in bitcoin core. There are workarounds that need to be done to achieve this; as was done by Yodice in this thread. Also to create segwit receiving address one needs to use addwitnessaddress. Lot of businesses just ...
In practice your invoice fee should be cited in the most stable and liquid of the currencies you support. Typically your national currency since you live with it anyway.
The contract would then stipulate that if the client pays in another currency that the amount that the client must pay is the going rate to sell that currency back into the primary ...
Creating a new address for every transaction (not just every single client) will allow you to maximize your payment tracking capabilities.
In case you have a single address for all of your payments it's really hard to track who sent you what. This will start changing from 0.9 on, but for now we have to stick to what is already implemented.
Having one ...
(Disclaimer: I work at BitGo.)
We rolled out segwit support on September 13th for all of our customers. To start using segwit, customers had to only perform a software update and in some cases update the API call when they were previously explicitly requesting non-segwit addresses.
By September 19th, our customers were creating more than 13% segwit ...
This isn't possible.
You can use those arithmetic operators to compare any numerical values that you can get onto the stack - they are not inherently restricted to signatures and keys. But you would have to get the relevant data (output addresses, output amounts) onto the stack in the first place, and there is no opcode to do that. The script doesn't ...
Bitstamp and any other exchange are companies and so can be insolvent. If you transfer $1000 to them in exchange for bitcoins. Until they send you the bitcoins they are in to debt to you for that amount. You could take them to court to recover that if they failed to provide the bitcoins or a refund. The court could issue an order allowing the companies ...
Cash. It competes with cash.
All of these things (prepaid accounts, debit cards, bank accounts, money transmitters, etc.) are sophistications built on top of cash in order to facilitate the transfer of cash from one entity to another. It's not easy to carry cash, nor is it safe to keep all of your cash in one place. It's not feasible to give cash to someone ...
Bitcoin transactions are "pushed" by the payer. There is no way for the recipient to "pull" payments.
You should use a new address for each customer. That way you can see who paid their subscription fee by checking which address received the payment. However, the customer would still have to repeat the payment every time.
There are some fundamental legal problems with this, as the Post Office is a creature of the Constitution and thus a creation of the United States government. It's not at all clear that the Post Office has authority to engage in brokering financial transactions. It's even doubtful that Congress has the power to allow the Post Office to do that.
That said, ...
Suppose you go with just using one address. Now suppose there comes a day when two different customers make reservations that have the same price. But you only get one payment to your address. Both customers claim to have paid. What will you do?
No. I don't think there are any good services that will allow customers to pay with fiat and have you receive Bitcoin even if you were okay with completing KYC, but regardless, no legitimate fiat payment processor will allow you to stay anonymous.
According to https://legal-or-not.com/bitcoin/egypt-bitcoin-status/, Bitcoin is legal in Egypt. On the wiki for list of countries on stances on bitcoin, Egypt is not listed.
In 2016, an Egyptian dentist was arrested for trading bitcoins for USD. Note, he was not trading bitcoins but rather exchanging them for USD. He was arrested for scamming, money ...
you could use multisig wallet, e.g. Copay - a secure bitcoin wallet platform for both desktop and mobile devices.
Check out miltisig use cases:
m = signatures required to spend
n = signatures possible
m=1 and n>1
Could be used for small group funds that do not require much security. Least secure multi-sig option because it is not multi-...
[...] how to found a company and deal with tax issues and other related human resources issues like payroll.
I don't think such sources are currently available for one simple reason: up to now the bitcoin space is mainly unregulated (including the issue of payroll).
The debate of bitcoin in the legal system is just in the beginning. It's not even that ...
This question is too vague, like asking list of companies that use arrays in programming. Colored coins are programming abstractions(just a type of data structure) and when truly used for a technical reason(not for crowdsale) they are under the hood.
(At work, I have used it as a mechanism to account for scarcity of a resource.)
Currently currencies are limited to three-character codenames, so although this can be done and will work it will probably be useful to establish some convention(s) that will help people to not get too confused.
For example your examples seem to amount, in general, to "store credits", like airmiles or giftcards in a way. Thus it might be better to use a ...
Why would you need to reimburse a customer? They should give you exact change and there's really no reason for them not to. I would recommend creating a daily cold storage wallet to receive bitcoins and then using some kind of online wallet service with a watch-only address so your employees can see the new deposits but they can't actually withdraw any of ...
Blockonomics recently introduced peer to peer invoices which are perfect for freelancers/contractors to maintain security/privacy. You can invoice in any currency and it would show BTC converted according to rate at the time the payer opens the invoice.
The contract language to use is along the lines of:
$N converted to bitcoins using the prevailing exchange rate [obtained
from source, such as 24 hour weighted average] on the date that
payment is made.
I just set up a very website that shows people how they can earn Bitcoins, it's simply called Earn Bitcoins.
Under the downloads section there is a free, easy to use PDF guide that shows brick and mortar shops the advantages of accepting Bitcoins and how they can easily integrate it. Please feel free to use it. I will also publish a print version. The one ...
It competes with a whole bunch of things, but the most important ones imo are:
national currencies (USD, AUD etc)
electronic payment methods (paypal, credit cards etc)
commodities (gold, silver etc)
