Well i mostly used ethereum especiall joining ICO's i can store all of my tokens without a doubt of losing it but bitcoin for me is still the king.
Yeah, bitcoin is still the king of crypto currency and i don't think other coin will replace it. Bitcoin has the biggest price than other coin and its still more popular to all of the coin.
Yes bitcon will be the king and we all know that ethereum will be next coin because it has lot of features and we can use it especially buying erc20 tokens
