The idea of investing in weak currencies just because they are cheap is a bad idea, most of them will never recover, investing in them is like you expect your luck.
Those are shitcoins and i will never invest on that again even if its a cheaper one. We have to start investing on cryptocurrency and start supporting it because this is the future of an online currency and a good blockchain technology. This is the best time for me because the market will start to recover again from its low price, but its should on a best cryptocurrency to have profit or else ended up losing money on shitcoins.
Any time in cryptocurrency market is a good time to invest but it would be more perfect if we start investing in a potential coin in time of dips. It does not matter if its price goes lower after buying it because if it has really a huge potential, it will always recover its price and brings profits to us once bull run comes.
