My current favorite coins are Dogecoin, Tron (TRX) and Stellar (XLM). because in my opinion these three coins have the best platforms in cryptocurency history and have good demand and volume all the time. for now I only hold TRX and XLM because I have sold Dogecoin and have given me a big profit. and I think XLM and TRX will also experience good increases in the future.
