We can't blame them for trying to make a fast profit,
besides, not all of those who buy Bitcoin when it starts rising succeed in making profit.
They have a bad effect on Bitcoin because they make everyone else
look at this revolutionary technology just as a source of income.
bitcoin has changed its function, has become a commodity that is traded, and they will benefit, if things like this are allowed then the future of bitcoin can be less good, you should start socializing the use of bitcoin to use in all trading activities, if bitcoin used as a function, bitcoin can become an alternative currency in the world.
