Don't get me wrong on this one but the first two projects have close ties to Binance and I'm not touching anything that they are financing or supporting. On the other hand, I had a look at Base and I love the idea since elastic protocols are just popping up. The problem here is how to incentivize people to hold rather than to sell.
Badger DAO is doing the same thing with the Digg token that will be elastic and pegged to the price of BTC. Right now they are figuring out how to prevent early receivers from selling it constantly and inflating the token to infinity.
All in all, elastic protocols will be very interesting to follow. As for Travala and Swipe, I will pass this time. Glad it is working out for you though.
