there are so many cryptocurrency which has low transaction fee like dogecoin,digibyte,bnb,dash but instead of all these coins I'll be prefer tron because it's transaction speed is much for faster than any other cryptocurrency
Yes, when talking about speed, TRON is indeed a little faster than the transaction speed of all the tokens that you mentioned, but the difference is not too far away because they all work on different transaction blocks, respectively.
I think regarding speed in making transactions XRP is one of the altcoins that does have a fairly high-speed and with the presence of xRapid, XRP has a speed compared to transactions that occur in several other altcoins and the transaction fees that we spend are not too expensive, that's the reason I personally, in every sale of tokens or coins on the market, will convert them in the form of XRP before I exchange them into the local currency of my country because they are fast XRP transactions and have cheap withdrawal fees than ETH or other coins that have a slightly more withdrawal fee high.
