How will cryptocurrencies fare that mainly focus on tipping streamers and other entertainers online? For example, a coin with a function similar to Bits on Twitch, but with monetary value. Even if this market is small, I think it still has potential to grow as there are few coins that offer such a feature. The only one I can think of is 2Give, which provides a similar function. Are there any competitors you know of?
What I can say about the tipping "industry" is that it is very much alive and well. Dogecoin, despite all its criticisms, will continue to serve this main purpose. Just look online at any casino or place that allows Doge, and see people tipping it all the time. Even giveaways still do this. But considering purely "artistic" tipping, there are a few alts. Artcoin, if you must, is purely based on this.
