- First mistake I made was, that I bought Bitcoin back in 2011 and stored them at Mt.Gox. I used them just for buying stuff in the Darknet and never tought that they would be something for long term investment. I lost all of them after the exchange closed over night. So --> Never store Coins at an exchange!
- Second "mistake" was, that I bought "not enough" Ethereum back in 2016, in my opinion. I know, if you let the greed take over, there is never enough...--> If you are convinced of a project/coin/token, invest as much as you can spare
- Third mistake was that I invested ~ 150 € in PACcoin, which was cheap and there was a huge amount to buy. But I didn´t made any research, and now I know it is more ore less just a scam/dead coin --> simple: always do research before you invest in a coin/project/token
