Bitcoin and Ethereum all is better crypto currency. Bitcoin is first and eth is second coin volume in coin market cap. btc and eth is best for long time hold every day this coin price up and up.
Well, In terms of holding cryptocurrency, I prefer to hold Ethereum because bitcoin's price is not well at this moment. Bitcoin is good in long time investment but i think that this time, Ethereum is much profitable. In terms of signature campaign, i'm more on altcoins rather than bitcoins because bitcoin is decreasing nowadays.
