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.
The truth is that many people was expecting to sell off on the 100k mark and then wait for the price to dip again which to some extent isn't very wise though because the price might just not get to that particular price you are hoping it will and that can make you miss out on so many opportunity to continue buying if you have bought before.
Bitcoin buying and holding shouldn't cost any hassle if you really see the future because selling and waiting for the dip isn't a good idea even though at some point it's clear that the price will fall .
