For me best alternative for faster and much cheaper transaction is through the use of ripple. Usually it only requires 0.5 xrp for a single transaction no matter how large or small your input is. However, this altcoin is centralized, so there's a good chance that it will not be added to new methods of deposit/withdrawal. Even so, I always like to transact using xrp because it is cheaper and way faster (just for transaction not for holdings).
There a couple of altcoins that are interesting with low fees and fast transactions. Ripple is one of them, but also doge/trx/bnb/ltc are interesting.
Good that Duelbits will add ltc, but the faster they implement it, the better. This will drive extra volume to the site.
the most important thing is we already have other alternative coins, isn't this a better option? Indeed, the more coins that are added, the more it pushes the volume too, but I think Duelbits will think of other things even with the features that have been implemented before.
The XRP that I use often is one of the habits for gamblers with faster transactions, not only xrp, many others too, but I think duelbits with just a few minutes can be credited immediately, even with faster withdrawals.
Maybe we have forgotten btc and eth
