im prefer to buy more on etherium, if you really want invest, hold your eth and btc until 2021, you will get big profit like 2017 did.
Those that are able to hold Bitcoin and ethereum from now till the end of the year should be ready for big profits by 2020. The truth is that it is hard to keep holding when reading some of the experts analysis about the market and that makes me to depend on the personal judgements I hold about Bitcoin and ethereum. Monero on the other hand is one of the best coins to invest now because I also believe in the future of monero too.
