What advice is worth passing out to people who have lost their Bitcoin more than once and are on the hedge of giving up?
What I can say is that "please forget about investing in Bitcoin if you can't change the way you keep it". Getting hacked more than is not usual anymore, there is certainly a problem for us, and if we still continue doing this, the same thing happen again. So, it is better to move on or make someone to keep while using our money instead of keeping it in our hands. In some instances, if we can't do the right thing, might others can do well. I'm sure it work provided that we choose a responsible person as well.
When a wallet with BTC or other cryptocurrencies is hacked and these funds are stolen, the attacker understands that he can continue to do this because he received a “reward”. If everyone who uses cryptocurrency takes better care of their wallet, passwords and other things in financial security, then they will receive these “rewards” less often. Therefore, protecting each wallet is important for the entire cryptocurrency community as a whole.
