That's a great question! What I do first thing is take out the initial money invested, this way removing the pressure of gambling, whatever goes up and down, I didn't (technically) invested anything anymore.
Personally, it helps me make better decision as I remove elements that might affect my decision making..
Then there is what you said, "is it all worth it" that depends on your why, why do you spend time learning about that, for the future, for your family..etc whatever your "why" is.
Plus, if you make good decisions and "luck" or the events or whatever you can't control doesn't pan out, you won't be filled with regrets I think,
That being said, I think the outlook is really great for cryptos vis a vis the next few years.
Yeah, I've done that with PIVX already. All the PIVX I own is profit and I probably should have sold to re-enter at a lower level, but... I just haven't been able to. Maybe I just like staking. :)
So much comes back to our why. For me, at this stage in my life, my why involves supporting projects I think will make a big positive impact on the future while also (hopefully) becoming financially free in the process at levels I've never known.
The only regrets I think I'd face would be if I sold something I believed in and then bought it back higher or just watched it go be successful without me.
Yeah that risk always exist.. Maybe by keeping a stake no matter what in the things you believe in will be the right call I think.
But yeah, there is always the gambling element since no one really knows. Part of life I guess, chance that we can't control.
Great WHY btw. I hope you keep reaching those levels man!
