If done right, trading in Ethereum is just as profitable as investing in Ethereum. We have to do everything right, if we do something wrong then there is very little chance that our results will come in our favor. Ethereum is a very important coin in the market, so if an investor has a long-term plan with this coin, then it is definitely okay for him to do that. I did trading or I invested it's not the big thing but the big thing is whether I did investment or trading properly. But if I have enough money then of course I will invest for long term as well as I will try to trade with small profit in short term period.
