Re: What if someone forgot the key to their bitcoin wallet ?

What are the measures to keep your private key safe and in memory ? Are there any alternatives to retrieve the key back ?

I dont think to should believe your memory, write it down somewhere. Better to have it on paper in printed way, because your PC can be hacked. Put it in safe place, do several copies.

That is true, the best way is to put it in some "material" way cause this is the safiest option that could be done in this internet era.

I think if it's necessary, we can buy deposit box in the store so we can make a print of paper wallet and then we can save it in that box and we don't have to worry from the hacker or other people that might want to steal our wallet. I think its more safety than to use notepad or write in other paper because it can get burn, dirty or other else.
