Recently bitcoin and altcoins has risen rapidly, so i think this is not a good time to buy now, their price is so high now, you should wait until they drop then buy it, their price are very unstable so you should be patient before using your money in bitcoin or altcoins.
I think only Bitcoin price increasing, all other altcoin price is completely down many people are worrying a lot about this downfall, maybe it will take some time to get recovered from this downfall. I thin crypto market is like that and almost all market unstable.
