I think it's a good choice to buy this altcoins but we are still in a bear market so don't expect to gain that much profit this 2019, i feel that 2020 would be a good year for cryptocurrency and hoping bullrun will commence.
I hope people start accumulating cheap altcoins now because once market start to come life. There are a lot of low value icon that has good product but only few people are noticing them but once we are done with bear market some of this alts will gain and some of them going to have no value at all. Just do your research putting money on alts.
Be careful of buying alts, most of them has no actual products raised in blockchain and won't gather demands from public. Choosing alts cannot be by multiple choice but the actual knowledge itself which we absorbed through legit information coming from their crypto platform. The reality behind each and every coin cannot be determined unless you have concrete evidence that this coin had with long term activities in the market tradings.
