What the fuck is wrong with you? Nobody knows that shady ico, dont put a single buck in there because it sounds shady as fuck.
Crowdholding ICO is also good.
Of course that you should keep investing a lot in bitcoin, it is the only crypto that gave a lot of profit to the early investors.
Just look at the charts, litecoin was around 0.02 a few months ago, and it was still $50 by that time. Now it is upto $100 each one of them, but the price is near 0.009 each.
if all the holders just kept their money in bitcoin, they could have more than $250 at the moment, just for a single litecoin. That is why i will ALWAYS prefer holding bitcoins instead of altcoins.
Bitcoin will die someday cause it has old technology, it is very hard to use. New alts with strong potential will overcome BTC (ETH may do it next year).
