It's worst idea ever ask here about predictions of price BTC. Especially if you want to invest huge money in crypto.
Even professional analysts can't predict this. Since the price of BTC depends on many factors. Just for the record. If you asked me, I would say that now is a very good time for investment. Because the market has been falling all this year.
You advice to buy when prices are low like this year. This type of strategy is commonly known and it doesn't always work. Btc trading requires trading experience but betting on someone's advice is bad habit which can lead to gambler's fallacy. Gambling is dangerous like trading if you have no idea what you are doing.
