For me it is now bad to invest in bitcoin. because bitcoin today is very expensive. But there are still a good way to earn, there is a or of altcoins that we can choose and we only need to select a good and promising altcoins that is so cheap for today and hold till it rise.
Crypto currency is very promising despite of high price of most popular coins today but still there's a lot of opportunity to be profitable if we start investing today, crypto is volatile and that alone we can make profit out of its volatility and if you have courage for long term investment then that sounds a little risky but all i can say is that there is more percentage of gaining profit than lossing.
