Bitcoin for me is a "savings account". The tx fee is certainly important, but more important is the long term value appreciation. I have changed btc to other cryptos to spend them, so I pay less fees, but Im not holding other cryptos long term.
If anything, the crash last March has proven that BTC is not a safe asset and not immune from a global financial meltdown. Other way around - its very sensitive to it actually.
In the old days, the very point of a savings account is that it keeps the value stable, and pays interest on top. The more long term you save, the higher the interest. Compounded.
