If we observe the charts, there is always a trend of price increase in all (or probably most if not all) of altcoin or everything that has value everytime the year ends. Now if one do want to do trading would it be best to do it per year? and if one does this, is there a way to identify which altcoin would yield the greatest price increase so that at the start of the year you may have the time to prepare for it?
No one could know, but trading long term is not a bad idea. In fact if you took that approach at all in the past you'd be flying. I think ETH has a great chance of coming back when sentiment turns positive again, that's my shout.
