That's what tends to happen to all these services, especially post HF19. To some degree they become outright arbitrage for those who feel it's worth it to pay X for the chance at approximately Y. Pre HF19, the more "vote power" you received, the more "valuable" those votes became, which was a unique value proposition in itself. Sadly, that aspect has mostly, if not entirely, diminished at this point. As always, buyer beware, and do your due diligence.

For example, I noticed very quickly with booster that a few of the first people early on got HUGE payouts. Within a day, the arbitrage was also mostly gone, with 1 SBD returning approximately 1.5 SBD give or take. Still not bad, but that's perhaps an average, and with all the various price fluctuations, still tricky to quantify with all the complexity and "moving parts" involved.

However, if you get lucky some morning at 3am when people have "given up" on booster, who knows, you may get lucky with a near empty pot, just like catching a great low bid in a wide spread market! Just gotta keep on top of it, easier said than done of course! :)

I've written so much here now, I think I owe it to myself to turn this all into its own post! lol
