Is it the time ?

Hello guys, i’am kind of new to the bitcoin world , and thought that the best idea is to ask you guys. 1) What do you think ? Is it the best time to buy BTC ? Or will it go down even more. At the time i’am writing this , it costs 20501. I’am not a trader, i want to buy & keep for later. 2) what is the best way to buy it ? Coin base ? Or binance ? Thank you very much. Happy to join
