Is there a particular minimal amount of Bitcoin one is allowed to send?
According to Paxful
Before making any transactions or depositing Bitcoin to your Paxful wallet, it is important for you to know the minimum BTC amount allowed by the blockchain network for a transaction.
Currently, the smallest amount of Bitcoin you can send or receive in a transaction is 5460 Satoshis, which is equivalent to 0.0000546 BTC.
One of the reasons behind this limit is to prevent spamming transactions.
Although Paxful isn't Saint Bitts LLC (owner of Bitcoin.com) they are talking about Bitcoin network limits, not proprietary company limits. So it applies. See also What's the minimum transaction with bitcoin?
To send smaller amounts you'd have to use something like the Lightning Network (LN).
Currently 0.0000546 Bitcoin equals approximately 2.71 EUR
Your 0.001707 BTC is larger than this limit. So this is not the cause of your problem.
I keep on receiving the error at confirm "Insufficient funds for fee"
Take the transaction fee into account
"Insufficient funds" is an entirely different problem. When you send x amount of money, for the recipient to receive x you also have to send a transaction fee y. So the amount needed in your wallet at the start is x+y.
The size of y depends on
- The complexity of your transaction (especially amount of small change rustled up to make the amount)
- How busy the network is
- How long you are prepared to wait for the transaction to go through. Minutes? Hours? Days? Weeks?
Many wallet programs help you to choose an appropriate fee. You can also use a search engine to find sites that report on current fee-rates.
