I will choose Binance coin, XLM, ETH and Tezos ... these are the best altcoins in 2019 and it will certainly be pumped strongly in 2020. Previously I had held Matic for a long time but after It collapsed last week and I lost faith in it, along with all the IEO projects at the Binance exchange.
The above-mentioned coin is very good for the long term because the short term we are seeing the prices are going down very quickly. Instead of focusing on the short term we should aim for the long term and it will surely help us to reach our desired targets.
