I think It's not. Bitcoin is serving huge oppurtunities okey but I think ICOs and Altcoins have more and more... 
For me it's a big yes, holding a bitcoin for long time is very profitable to do to have or to make a lot of money, even the price of bitcoin was not stable it is till okay to hold it for long time because it has a big chance to pump its value very high and when that will happe we will make many money.
