We are delighted to have you here on this forum but however the idea of asking for whom will teach you crypto trading will not be easy or possible to find  because crypto trading has it own challenges and some persons can hardly understand it let alone teaching people, so Bitcoin is the only investment that has a high concentration here, secondly we have a board for crypto trading were everything concerning it are being discussed and we also have a gambling discussion thread were you can ask such question but however I don't even no if gambling is something that should be taught because gambling is an unpredictable game just like crypto trading but you can also visit those gambling threads to read about it, however whether crypto trading or gambling applying risk management on those areas will be good for you and you should also do well to get yourself loaded with the reading and knowledge about those areas you have in mind because they are not something to rush into when you don't no anything about it, so by doing more reading and visiting those threads you may even come across those who has different opinion about it and through their experience advising people about the less risky way that would help them, so those are also the things that would make you have a broader pictures about those areas.
