Everyone has their opinion on a particular issue. buying btc at this time is good, and selling bitcoin at this time is wrong and also holding btc at this time is good as well. So I will use 50/50 statistic on this matter. Now, if I used 50/50, I will use buying and holding byc now. If you have the fund to buy now. you can buy then you hold the ones you have bought till the market goes up.
