Know that, if we take ETH and hold it for some time and trade, we see a good profit. But many times it happened that after buying ETH, if its price drops, we have the possibility of loss in the trade. Due to many movements in the crypto market, we should trade wisely.
Should we invest long term??
Seeing the history of this Ethereum I have a personal opinion that this Ethereum is suitable for an investment long -term, just look at the whole chart from Ethereum slowly rising as well as Bitcoin. Seeing the transporization of the POW system changed to a still Ethereum post, this Ethereum is the best choice for the Cryptocurrency community.
Trading may be suitable for the short term because it is taken from a glimpse of up and down, buying Ethereum when the price goes down and sells it when Ethereum rises, but for the long term I will choose Hodler for Ethereum. This is just my personal opinion because the ecosystem of Ethereum is extraordinary.
