Thanks, makes sense... I've got a little bit of BTC, but I'm heavy into ETH. I own some other altcoins, but they're all well established ones (all listed on coinbase).
If you like ETH, you can buy it at this time without sacrificing anything else including BTC, because BTC and ETH are two things that are equally good to hold on to for a long time as they always give good surprises especially this year.
