Yep pretty solid advice. There is one testament rule when investing in a high risk market such as the crypto market, you have to keep your emotions aside. Also, without empirical or statistical research backing the trading move you want to go ahead with, you should not go forward with it. The crypto market is far too volatile and it's always a challenge to stay risk-averse. So, only invest when your mind is peaceful, calm and calculating. One wrong move and you will lose it all.
