Assuming that, nowadays, BTC's hodl could be as long as 5 or even 10 years from now.
How long is a long time hodl in alt-coins?
For example, if I'm looking to hodl ARK/STRAT/XMR, what is the right time-frame? is it just for a few months to a 1 year, or can I leave them for 5 years with the hope of weathering the storms and coming out strong?
And besides, do these kind of coins have a 5-10 year lifespan?
I think whatever under 2 years is not a HOLD.
as I see you have bag holders, day traders and investors.. You probably know who first two are. Investors are the ones that invest in coin when is cheap, so accumulate in phase when something is planed. and sell soon after that gets implemented and pick up profits.
