Maybe he is really not that familiar with bitcoin and just tagged it as a 100% faith. He must’ve invested a huge amount when it was at its peak and crosses his fingers hoping it keeps on increasing its value, now that’s faith. Bit in my opinion though, it is a matter of self discipline and you have to educate yourself too on the coins you are investing. As they say, knowledge is power and so if you have enough knowledge; you have the power to control what coins you want to invest when the value is low. 😉
