KOIN: I stopped mining after 5 or 6 days. The first and second day was good, and then the bigger miners installed themselves. Had 2 laptops running with a total of 4 MHash or something? At start KOIN was 3ct on Uniswap; After a few weeks, it went down to 1ct and kinda stayed there. Others started to notice as well, the big 'cafe' miner dumping all it mined. In the Discord community, it became clear many stopped buying at higher prices than 1ct. I would not suggest trying and mine. Ether fees apply with each proof. A few big farm miners, of which one is this 'cafe' one. With some small PC, it's way more efficient to buy at Uniswap instead of trying to compete :)

AVA: the interesting part is, they give AVA to all those purchasing through the Travala shop. 2% of the purchase value. Apparently, they had a pool of tokens for this, but this run dry. Now they buy AVA from the market to continue this freebee. The perfect method to get none-crypto people acquainted with crypto (yes, also those paying with fiat receive AVA). Their gross revenues are increasing a lot, even in COVID times. Check the blog of Trumpman, he has some post about this. This is the first (and only) compelling mass-market service I know linking in the crypto space. The Travala company had crowdfunding (fiat investment) running late last year, equity. I was just a few days too late to jump on that one. Was overfunded quite a lot. Regardless of my participation, also that one shows 1) how serious this company is 2) the value of what they do.
