Hello,
I bought ethereum since May and June 2017.Got in @120 and 275 and my capital has doubled since. I'm really long on ethereum but i was thinking about sell a little bit to diversify my portfolio because for now i'm all in ethereum or sell everything to buy the next dip but i am not sure it will worth it or switch to bitcoin.
What are your thoughts on that ?
My suggestion is definitely diversify your portfolio to take advantage of potential rises in coins other than Ethereum. Going all in for ethereum can pay off handsomely and i do think that it'll go to at least 0.08 btc again this year, but there will be dips along the way that you can buy in for less than you sold for.
For example you could sell 20% now, since ETH just had some pretty nice pumps, then buy in when ETH falls back to 0.06 BTC if you're really long with ETH.
Or as i said, you could diversify these funds into other potential alts.
