In my opinion, Litecoin is the best public blockchain transaction currency.
Transaction fees are low, transactions are usually very fast compared to BTC and it's almost universally accepted.
The only downside is that the development is centralized. But since it's not really meant to be anything more than a currency, that should be fine because not a lot of additional development is needed.
If you want to save money on cryptocurrency transactions, using LTC is the way to go. Show Less
