This will always be true. So long as people just try to grow their absolute BTC investment, and not worry about what the exchange rate is in terms of fiat, then they can only succeed (unless they're complete idiots).

Don't focus on how the market is "crashing" when all cryptos are down, just focus on making logical investments with your BTC. If you can't afford to convert fiat to crypto, then just invest in crypto, and trade sideways.
