where in the forum to find legal platforms
There are many legal platform which being trusted by most crypto user, but it depends on you. What your strategy to make an income, you are not suggested to start a business without you knowing what to do.
Like platform that you mentioned, I guess it is just the beginning for those who want instant money become someone who only knows crypto currency and just walks away because the losses he has experienced are so many.
There is no profit consistent, sometime you will get money and you will lose your money on this field. Even when you try to stake some altcoin out there there is no guarantee you lose your money.
