The big lesson I received through altcoins is "high profits come with high risks", I had time to enjoy projects through ICO, lending,... 2017. And indeed it is still exciting. It's worse than gambling, but teasing it fosters greed and makes me depressed when I lose everything. So when I look back, I still feel really happy because I realize the truth that the opportunity we create for ourselves and being able to take advantage of it is also for ourselves.

For me, the current altcoin environment is only a short-term investment process because I am aware that when my capital is larger, I will not prioritize risk, so I will prioritize bitcoin more in my portfolio.
