Buying bitcoin at the low price below 4000 dollars we can expect the least price which is available for crypto traders at this price better to gain as many btcs once the bull run start we can see higher prices like before previous highs may touch in this year probably
The lowest price we buy gives us with the opportunity to profit at the the earliest. If you've made the investment when it was around $10000, now they need to hold on to reach the price above $10k which takes more time. For the one who invested at a price less than $4000, it is possible to profit earlier and there isn't need to have patience.
