The biggest crime in Crypto currencies are the fact that private centralized institutions hijacked the whole experiment and then caused all these problems. Satoshi did not want people to do P2P transactions via 3rd part centralized services, he wanted people to trade 1 on 1.
These centralized services used exploitable code and hackers and thieves quickly realized this and they targeted these vulnerabilities. So Bitcoin was not responsible for these hacks, but rather 3rd party services with weak software.
This! Play it safe, Use a phone wallet to store you coins for the long term (write your seed in a paper!) and dont use any centralized service or exchange as a mid or long term wallet.
