No regrets. Take in count that I started very early, so I'm sure I helped for liquidity in the early steps of LN. After all, I helped quite a lot routing many payements, believe it or not, more than 200k payments went through my node, which is quite a high number considering the low liquidity (8 BTC in the beginning and then 2-4 BTC in recent years) in comparison with bigger nodes.

It's just that we have come to a point in which individual nodes are not needed any more, the network is very well stablished, and the work and worries it requires to maintain a node is excessive for an individual.

Also, I have learn quite a lot and I can say now that I know very well how Bitcoin and Lightning works, and I am very confident in technical matters.
