You should buy now since the market is bearish, it could be a correct time to fill your bags of crypto since the market is down and you can buy low and sell high in the future. But what you buy should be hodl and kept so that you would earn profit in the long run for a long term investments. But for me, i would definitely buy coins with less than a dollar, so that I could've earn a lot of profit when the market is bullish again.
