He did used probably a bit for this. Getting the price of room token for 0.05$ for 1 eth and now it's worth more than now like 100x. This is for sure a bot equipped trader.
Either its customize or what but one thing is for sure this is expensive. Not sure how it works. But there are probably pros and cons for this. Many are offering it randomly but beware of scam ones. They scattered around.
