No it is not an achievement from gambling because you did not gamble to get the money that you have made from promoting a casino on your profile. Signature payments are like your salary that you receiving for posting on the forum and if you used the money for gambling and got more money than you can say you have achieved something from gambling which is more money. When you then use that money to do other things or investments, that is when you can say you have achieved other things from gambling. If you do not want to risk the money on other investments outside of cryptocurrency, you can buy Bitcoin or buy other altcoins that you like but do not think that altcoins can give you more profits like Bitcoin because most of them don't give their investors any profits.
Yes, getting money by gambling, with getting money by becoming a participant in a gambling signature campaign is different. So, you @Ojima-ojo do not get anything from gambling, because you only get something from your signature campaign. Unless,if you actually make a deposit in the gambling platform and then you get a win so you can withdraw and you can also buy something from the results, then you get something from gambling.
But for me personally, I have been gambling for a long time and of course I have gotten a lot of things from gambling. A small example in the past when I got income from gambling, until the profit I got was able to make me buy a smartphone, laptop and also some other electronic devices. But as time goes by I just enjoy it and use it more wisely.
