If you want to enter and buy bitcoin, maybe now is the right time. That's because prices have gone down very far, don't wait for prices to fall again because if at any time prices go up you will lose the opportunity. It's better to immediately buy later if the price drops again to buy again. I am sure that next year prices will recover and continue to rise.
Ofcourse yes, this opportunity will never come again if the value goes up and a lot of them will miss the chance if they don't buy coins in cheap prices now. If the price soars up then a big margin is waiting for you.
