Hello .I do not think if the owner for 2 to 3 years is good, you can buy it at the beginning of the year and sell at the end of the year will earn a bigger profit.
I don't believe holding coins for 2-3 years long will maximize profits, it will exhibit a platonic state at some point and that would be a waste of time IMO.
A year of holding for me is the best way to go. However, going for the big guns like BTC and ETH then maybe yes 3 year might do.
Exactly what this guys have been saying. It is not wise to hold for very long if you are eyeing for bigger profits. A year can be a good barometer for seeing profits at hand.
However, there are inconsistencies about long term holding for even ETH.
