In my opinion. prefer to hold and save your ethereum than you sell or convert it to another altcoins such dent, waves, ppt, start or whatever anymore
because ethereum is best altcoins to hold for longterm, every year ethereum has good increase high price and ethereum is used by platform it makes ethereum has good price in the future and always interesting for investor
maybe in terms of market capitalization eth is the best alt, but in terms of development many will surpass because ETH blocks and networks are already very numerous and heavy plus ETH does not have a maximum supply.
we won't know how fast the ETH will send later when the supply has touched 200 million or more
