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.
There is only one Bitcoin and there will be no next. Yes it is not bad to invest on some altcoins but thhe majority of investment should be in bitcoin. We all know that altcoin fluctuations mostly ride wih bitcoin.
