At current market prices, I'd say BTC is still a bargain. But it can go even lower if the "bloodbath" persists. There's no way to tell if Bitcoin has reached the "bottom". Your best bet would be to DCA (Dollar Cost Averaging) Bitcoin and "hodl" until the dust settles. I'm sure BTC will reach a new ATH after the next projected block reward halving. $250k is the most likely target. I'd diversify my investment into alts, just in case.
If we keep bargaining price with the market, we will fail to buy bitcoin at cheapest price as we will never feel satisfied and be sure that a price is a bottom price. Even it is a bottom price, we will keep waiting for possible lower prices and waste that bottom price. Hesitation to enter the market is a classic fault of people who want to find bottom price, time the market and they usually make similar mistake by feeling FOMO when price already moved far away from bottom price area.
With Bitcoin prices from $60,000 to $70,000, I believe that it is no longer to far from bottom area but if we enter from $40,000 to $70,000, and in a next market cycle bull run, Bitcoin just need to move up to $130,000, not yet higher than that, we will have very good ROIs.
Bargaining prices for enters too much will make us missing the train.
You are right quickest way to lose everything is to think that Bitcoin is get rich quick plan with true way of becoming wealthy being moving past beginner thinking into becoming long term buyer.
Buy and hold for profit, there is no quick rick chance with Bitcoin. If you can hold bitcoin, you will get profit like after some years.
