If I look at in crypto market now, I think if you buy btc now, you can got profits not much because in this end year maybe btc price up to 100K.
It already went $100k and those that have purchased at the top has to do two things.
1. Wait until it gets back there and if they are longing to get out, they have to sell at a higher price.2
2. While waiting for that price to get back there, what they can do is to accumulate even more while it's still below the price they bought in.
If you are looking how to get quick profit in bitcoin you won't be able to invest in bitcoin. It is only one who is looking in the future that won't be bothered about the current price of bitcoin to buy now or not. Real bitcoin investors don't get bothered about bitcoin price to invest, they buy bitcoin to make profit from it in the future and not to make profit quick.
If we are considering price to invest invest bitcoin sometimes we may be disappointed when the prices falls when we don't even expect because of the volatility of the market.
