My husband passed away a few weeks ago and he had a bitcoin account. Is there any way that I can recover that and transfer it?
I'm sorry for your loss.
If your husband is keeping bitcoin at a big name bitcoin exchange, you may want to contact the exchange administrator to inquire about the procedure.
If the bitcoin is outside an exchange, then accessing it requires knowing a very long password or a very large number, possibly starting with "0x" (meaning hexadecimal). It would probably be written somewhere on paper, but may also be hidden in a password-protected file or stored in a special USB or other crypto device.
If you have reason to believe your husband may have significant money in this, you should really find a knowledgeable friend whom you trust to help you find the access credentials for the money. Unless you are pretty tech savy yourself, you should strongly consider immediately selling the bitcoin for "real money".
On the other hand, if you have no evidence that your husband had money in bitcoin (other than, as you said, "a link that said Bitcoin") you may want to understand that there are a lot of people with interest in Bitcoin who do not hold a meaningful amount of Bitcoin.
Lastly, as said already, do not trust anyone on the internet. Do not give anyone any passwords or any numbers you do not fully understand until you get help from a knowledgeable friend or have educated yourself very carefully. It is extremely easy to steal Bitcoin, it is nearly instantaneous, and it is almost completely outside of legal protections.
Your question caught my attention I would like to try and give you some answers. First of all, I want to say that I'm sorry for your loss. You ask if there is any chance for you to regain access to the bitcoin so that you can transfer them. In short, my answer would be yes, it is likely that you can - if you have some essential information. You don't mention in your question if you have found any wallet files, passwords, words, or other leads that can help you. But if you have any of these things there is still hope. If you can't find the wallet file but have access to the computer of your husband, it's likely they are on there and there is help to get to find them. If you are tech savvy yourself, it's possible for you to start the process from home. What would hold you back would be the processing power of your home PC, since they don't have the power to test many passwords at the same time, the process can be very long, longer than you can possibly wait.
If you know anything about the password, for example, - Password span (how many characters) - Password language - Any numbers or special characters used - Did your husband usually make passwords by combining words or how did he usually come up with them?
Every detail will narrow the possibilities and shorten the search time. Some of the free softwares out there that you could use are John the rippers or Hashcat. You can read up on them online. Recovering passwords is something I do for a living so that's why I know one or two things about it :)
Also, as some people above have already warned you, don't hand out any information about your bitcoin to strangers, bitcoin is unfortunately easy to steal if sensitive information gets in the wrong hands. Good luck!
