I see some talk now about a different kind of speculating, buying tokens like this to get bargains when they're being dumped after people collect dividends, and then selling them just before the next dividend round. Apparently as more tokens like this come out, it seems to be making a lot of money for speculators. Seems too much trouble for me, though, but I suppose if you had a lot of money you could turn out pretty solid profits. Or you could just end up getting trapped if you're not experienced.
Yeah, if you can guess the right volume per month, the right time to dump (probably just after the time the dividend are distributed) and enter at the right moment the next month, there is probably a great opportunity. Or you can hold and have a 'steady' passive income. Right now there is Cryptopia, Binance, Kucoin and COSS that does this kind of dividend system. I think CEFS is the most undervalued and profitable coin now of all four, but I could be wrong.
