congratulations you just found and participated in a pump and dump scheme that has been going on for years in altcoin market and hundreds of other traders have been doing the same thing for just as long
just replace the work i put above (..blank..) with any altcoin name and you can say the same thing about them and your statement would be correct.

don't forget that you have only made that profit IF you dumped otherwise you will lose just as much and then some more when others dump on you
