For online means not unless you are looking for something that is recognized by the US SEC I don't think it will be a safe way for you to acquire them as most of them will most likely be illegally running their ICO in the US which will be bad for you. I guess P2P trading or direct trading to a person is something you can consider as this is something that most people resort to if they don't want their kyc to be given away. You must understand that there is also scams happening even if you trade directly so you must be familiar with it.
