it's not a gamble if you have a good measure of the odds of success
that's a bet
gambling is where you hope that you will get an undue reward

Ok. So investing sounds more like a bet...
that's what should prompt you to do it
vesting is really just a synonym for saving, or stacking capital into something
it is literally folly (foolish behavior, self delusion) to vest your resources into things you have a low chance of success in, and if you do it based on shiny sparkling lights and weasel words you are definitely a fool
like, my bet, when i first started doing Go programming back in 2016 was that it would eventually yield me something
i am now in a financial position that several of my respectod compatriots have a sense of envy for, because this is some serious capital i have acquired and as such i am confident that one way or another i can turn my sunk capital (which was some 8 years of hard work, at some points almost dangerous) as it is not sunk, this is welath i have acquired, my ability to write software that few spend such a large amount of time to develop... it's not talent, though my talent at thinking did help me pick this.
i don't think i have fully yielded as much as i could out of this either, my pay rate is probably pretty low on the market for what i can do... and partly this is because i want to apply that capital to something that has a psychic profit for me of promoting freedom and decentralizing power
