Now is a good time to buy any cryptocurrency you want, even Bitcoin, because there is still more time for Bitcoin to go up. LTC is going for a halving in like four weeks time or less and there is the possibility that the price is going to increase once the halving is done. And ETH will likely follow Bitcoin to the top. So there is every opportunity to invest now and make profit as the price goes up. I don’t even think that these three are the only ones that are going, others will as well be going up too. But LTC, btc and ETH are the big thing.
