ETH will have many big communities because the display and application are friendly, XRP I think not a crypto but still good choice. XLM TRON also have to buy in 2019 (my opinion) Stellar is very cheap, Tron also has many events and any event will get a FOMO from Justin
There were many potential coins to choose from, but it's hard to pick the good ones. We should determine the best of them, and like tron,xrp as well as eth I guess that's a wiser choice to complete your shopping list. Hopefully soon we will be able to withstand against challenging days of crypto, for the future of our holdings.
