Ofcourse bitcoin for me because it is the most volatile in most of the crypto currencies right now. but i am also looking in ethereum , im holding some of this tokens. that 2 crypto currency will have a big potential in increasing in the future.
I'm very fond of Bitcoin, there are a lot of people who feel that the Bitcoin currency will rise in the future and I believe Bitcoin will still keep its price in the market and be an investment. best for investors...
