What do you think about the idea of giving access via API to your exchange account to a professional trader (who shows profits even in this hard times), who will manage it and receive some % from your profits? Is it a common practice to do so? Do you know someone who tried this approach?
NO, if i be you i wouldn't do that. Traders not always get profit and when he get profit sometime it wouldn't happen to you. It is better to manage your assets by yourself, maybe you can ask his suggestion only and do it by yourself.
