Cryptocurrencies is casino by itself. And volume and activity just give you a chance to sell tokens. But it doesn`t give you any guarantee that the price would be nice.
Investing in casino looks the same as any other investment in cryptocurrencies. The main difference in such kind of investment that you can`t wait for 10-20-50 years. You have to change your strategy and tokens rather fast.
You can easily tell how the casino-based tokens are performing not only in the market but how they are accepted in the gambling community and
how good is their reputation, BFG and Owl tokens are two tokens that are well accepted by the community based on the players supporting their platform, there are casino-based tokens but nothing beats these two, and as long as these two are well supported it's worth holding these two tokens, casinos are here to stay so these two tokens are staying for long term.
I often hear such words about other projects. And often see how these projects disappears. I can`t say nothing bad about these tokens. But the team and reputation for the casino-based tokens is the same for all other tokens. I`ll not be surprised, if some new casino will create their tokens and steal users money. If somebody believes that casino tokens are good for investment - it means only that someone else will cheat with it.
