I've had quite a bit of discussion around ETH/BTC/XRP in
this thread and have been following and trading crpyto for the last 3-4 years. Personally I see ETH and Ripple (XRP) as the two major players over the next 2-3 years with possibly SIA as well.
Would I buy more ETH? Not at this price, I bought it between $7-$46 and it's due for a correction at some stage.
Would I buy more XRP? If it's a long term play sure, it's got enormous potential.
Would I buy BTC? No, it's horribly outdated and only serves as a currency pair for getting money in/out of other cryptos. Once ETH or XRP currency pairs are added BTC will no longer have a purpose.
Would I buy SIA? Yep, I think it's still undervalued.
All views are my own obviously.
