That's right, right now, when the price of bitcoin is in such a big decline. If it were me, I'd buy it!
Wait for 20K-25K in the next 15 day's.
Though predict in Crypto currency is so much tough and no one can 100% surely predict on Crypto currency but here I'm surely tell you that this will never happen. Except in this bull run this will never happen that bitcoin Price will get down at $20 - $25k. Bitcoin price was hit $30k yesterday but today its price is around $39k. So don't wait for that and buy some bitcoin now.
