Bitcoin will remain a strong force...it has more development on it than any other blockchain which means the present problems will be solved (or at least alleviated some). It also is the darling of Wall Street which will buy it a nice run over the next couple years.
That said, is it the best choice to buy? I dont think it is bad but there are better options out there. STEEM is one of them. So is BTS. Nevertheless, BTC will most likely triple this year which is a great return...under normal circumstances....in the crypto world, that is hardly moving.
