Lol, this is so true. I urge everyone to really put the majority of your investments on bitcoin to avoid getting REKT in the future. Well, you can still invest on some altcoin but at least the your portfolio should be like more than half on bitcoin, just saying.
Yes, for investment portfolio must be well and good. If you invest limited you can hope to back limited. So you should trade with vast number of portfolio and also have to be technical in trading. You also have to own research with investment otherwise you will go back and nobody can give you ladder.
Best of luck.
