Looking for advice. If I am helping my nephew get off zero and he likely has a very slow path of accumulating bitcoin in the years ahead, given his debt and lack of much extra after bills to save/invest, is he better off stacking on layer 2’s? I realize mempool is currently not full but years down the line if he doesn’t have a sizeable amount of sats, he could be priced out of transactions? At least that’s my basic understanding. Maybe it’s too early to be concerned with that? Appreciate any wisdom or corrections to my thinking.
