buy bitcoin prices at the lowest price even if there is a sell at a low price. but I think no bitcoin price is low because the price every year will surely increase so just need to be patient and not panic in selling it
I think that at this point you should consider carefully before buying bitcoin, can see that bitcoin prices are having very little fluctuation in the past two days and are showing signs of convergence. So if you buy bitcoin and at this point the bitcoin price is not going to increase and may decrease, the market is still down trend so anything can happen.
