The Tron ($TRX) cryptocurrency would make an excellent choice for a cryptocurrency-based donation solution for Twitch and YouTube streamers.
Boasting impressive transaction handling capabilities of 10,000 TPS (transactions per second), it is one of the fastest cryptos in existence today. In comparison, Bitcoin's approximate transaction handling capacity is only 7 TPS, and Ethereum can currently handle a slim 15-20 TPS.
Transaction fees on the Tron network will be 0.00001 TRX, which at the current price of $0.07 equates to $0.0000007 per transaction! TRX is one of the only major cryptocurrencies with essentially zero transaction fees.
Support and Backing
Tron is backed by many brilliant tech and business minds and has a massive community of loyal supporters including many Twitch and YouTube users!
Integration Timing and Benefits
Integration with Streamlabs should occur after the Main Net launches on May 31, 2018. Post- main net, many major cryptocurrencies will be migrating to the Tron network. $OCN and $GTO are two examples of many. This integration would allow streamers to accept donations not only in $TRX, but also in any other crypto built on the Tron platform.
