You don't have to enter the Bitcoin market when prices drop, joining now is also a good idea, Bitcoin prices are changing every second of the day. You shouldn't panic when you see the price of Bitcoin decrease because the price increase and decrease is a normal thing.
I guess the bitcoin and altcoin prices has started to recover and this is the best time to invest in the crypto. Also we are about to start the last quarter of the year and as per the old analysis, bitcoin prices raise in the last part of the year and also we are near the end of bear market , waiting for the bull market to start at any time from now.
