For longterm investment i would choose
1. Bitcoin
2. Ethereum
3. EOS
4. XLM
5. XRP
6. Cardano
7. Tron
and i will buy more since they still cheap for now and i hope my choice is not wrong and hope soon we will see bullish at market
As for me XRP has the greatest potential aside from bitcoin and ethereum which on many cases already proved a lot. XRP moves very high these past few months specifically the quarter 3 of the yeara nd gave a slight hype of its market. I guess holding XRP would be beneficial since it is currently overtaking the market cap of ethereum.
