For me, I use bitcoin to spend on my regular needs, by buying amazon gift cards. So this is money that i'd spend anyway. I then buy more bitcoin with my savings. I try to time it so that I'm spending bitcoin when the fiat/bitcoin price is high, and stacking when the fiat/bitcoin price is low.

What is your pubkey? I will consider opening a channel to you. I don't know how helpful it'll be though since I lack inbound liquidity myself.
