I would say until mid-march you can trade crypto, but sell them before April, as bitcoin halving is in April and bitcoin is going to pump. And its trend when there is a pump in BTC other crypto values drops.
It won't be a bad idea to buy some altcoins and keep or to buy for trade. Am currently buying altcoins coins for trade and am happy doing that with some few sats. Traders with little knowledge will be those who will wait for the Bitcoin halve before they start trade. Buying altcoins at this time will definitely yields more profit ahead of the big event May, 2020.
