I want to ask everyone who got into bitcoin towards the end of 2017 and is currently at a loss, like myself

What will you do when the market goes up and you get your money back. Sell or just keep holding?
I'm underwater on some buys since I dollar-cost average but I think BTC is a good long-term buy as a store of value. So the market volatility is irrelevant in the grand scheme of things. If BTC eventually becomes a global reserve currency, it should easily blow past its all-time highs.
