As these exchange sites are dropping BTC, all our altcoins are going dead. This is not fair. This is cheating.
That's not true and if it's true they need a lot of money by doing that
First of all price of many coins there are base in users like if they buy that in high then users sell in low so think if they cheat like the price is base on trading site they will pay a lot of transaction by that kind of cheat because they drop it on purpose
But still there always a possibility
