One thing we should understand is, that altcoin is an altcoin and there are no two ways about that, but then even though some altcoins are used as utility tokens they still perform in the market so for the sake of investment, casino tokens may not be the best option since there have less traffics in terms of volume and trading markets.
Either way, if we play it right in the market, there's always a profit in return. Treat these casino tokens the same as how we treat other altcoins in terms of making profits. As long as there's a steady volume, these coins are worthy for short-term trades.
Anyways, OWLDAO is currently on a nice run recently. Right now they are up 20.7% in the last 24 hours. Still -55.7% short during their All-time High last June but still with that increase recently in the current market state right now, that's a good sign that this token is still considered to trade by most traders.
