Gaining benefits from the wrong things is a very dangerous matter.
For example, if you win some money from gambling, you are likely to want to continue gambling, with bigger bets, and the outcome is predictable.
For instance, if a person gains some benefits through deception and trickery, they may easily become reliant on this way of living, but in the long run, it will ruin them.
One must learn to look at the long term, rather than short-term gains, as short-term gains are meaningless and can even be very dangerous.
Bitcoin and Ethereum, in the long run, are not problematic; regular investments of #BTC and #eth have not shortchanged anyone.
