So it is selling time to switch the profit to buy current hype coin like XRP,
Is it good to stay in ETH and waiting for whales to pump it?
Or sell it to pump other (like XRP or BCH or others)?
This is the best time to buy some alt coins . Look at their market going all green . Many good coins like electroneum , ripple etc are ruling the market right now after bitcoin . XRP seems to be a good coin looking at its ever growing pace .
If in future you witness that ETH is going furthur down then there will always be a good time to invest or convert ETH into some other coins , but do not loose your staked on ETH so soon .
