Just like heroin or crack cocaine, it creates an addiction.

Same as was gambling

Many in here seem to have been caught up in it, spending far too much of their money on something. Partially to get the dopamine rush of buying more coin, and partially to satisfy their gambling lust hoping to score big.

It is no different than the people gambling their savings away on the roulette. Right now we are at the point where they have entered the casino and have been lucky, so they are up more money than they came. But instead of quitting while they are ahead they genuinely believe that their luck continues.

In the end it ends bad.
