For now you can hope for the best, in the short term you can expect a small correction, but in the long term things are looking very good.
It does look reasonably likely that BTC will hit $100k this year. The question really though is whether it will hit $100k and bounce straight back down, or whether it will break through and hold above that threshold.
Big round numbers often cause a problem, I would think there's a good chance that if BTC hits $100k it will correct downwards very quickly. Long-term I'm very confident the price will be above $100k... I'm just not convinced that we'll hold above it the first time we break through.
I predict the same thing, investors are waiting for the price of bitcoin to break through $100k after that they will sell in very large quantities, so they can buy again when the price starts to correct. just like yesterday when the market broke through $62k, investors were racing to sell the asset so the market crashed at a very low price.
This is normal, and when we feel we are getting a big profit then selling is a good option, there will always be an opportunity to buy at a low price so that we can get the maximum profit, if we look at the current trend then I am optimistic that the bitcoin price will not go below $50k.
You are right, in fact it has happened to me that I want to buy cheap but I do not have the money, when I have the money the BTC is very high in price, so it is not worth it when you have a short budget, in fact, it is always good buy when it is below its last ATH, because in the case of BTC it is a guarantee that the price will rise, what should be kept in mind is that that money that is invested, the idea is to have it there and forget about that money until profits are made, and that is the difficult thing for many, because some want to make a profit quickly and suddenly the market goes down and the worst thing is to take the money invested in loss, knowing that the currency will grow at any moment.
