I think the "diversification" is an important part for most people's portfolio. Plus, it drops the risk if one of them goes down. If you get just one coin, and that coin goes down for a reason, that's bad, but if you get paid in multiple coins, and one of them goes down, the others are still up. Imagine if this place had Luna, then it would drop a lot, but all others would stay, would you rather get it all on Luna? That would be bad. This is the logic behind these people.
I still say BTC is the best, just get it with that, but I also understand why it's multiple ones. I feel like it is going to be decent this way and it has worked so far, and should probably keep on working for a while longer, at least until bull run.
I don't think it works during a bear market. I mean, only stablecoins can be used for risk diversification at the moment, while most other alternative cryptocurrencies just follow bitcoin quotes. At such moments, it would be great if the Betfury team added a feature that allows converting altcoins from daily dividends to BTC and USDT directly inside the platform.
