I only hold ethereum, bitcoin and xrp. The other older coin like doge that I hold before was previously converted to xrp, because even if I know that doge is a great coin, making a profit out of this coin will take a lot of time than making a profit in xrp.
The three coins are in the top ranking of coin marketcap and have great liquidity. Bitcoin and ethereum are the coins that are most sought after by investors because the transaction volume is fairly stable and tends to continue to increase
