I just read an article in which it was stated that once a bitcoin core developer was asked that if he voluntarily works to help the bitcoin network,then who pays him for that and he just answered that
"Bitcoin pays me, so I pay it back to Bitcoin with my time and effort.”
I think that it is due to these volunteers and not the speculating investors that bitcoin has reached such a tremendous progress today.
Yes, we are owe a lot to the those amazing devs for their tremendous efforts.
If you are here for the believe of this technology, and you have skills please do helps them, or at least by keep HODL-ing your BTC bag. That's the least contribution that you (and I) that can be contributed to this revolution moves.
BTW, does anybody know which exchange will implement LN except coinbase in several weeks? I think this is a good progress.
