Yes, I completely agree with you. I regularly buy some bitcoin. I try to choose a time when the price has fallen a little. I'm confident in bitcoin and therefore I'm not afraid to invest in it
It is good to invest in bitcoin and other crypto currencies but never have a blind eye on your investment as you never know what the future holds for all the alternative coins you have at the moment as there might be a time when all the gas run out of alts and bitcoin will be the sole survivor.As long as you can make money with it,i am happy with it,but i am not going to risk more than i can .
