Really depends on what your plan with the coins you are going to buy. If you are planning on hodling it for a long time (I mean years) then I'd go for bitcoin and stable coins but If you are looking to be doing daily trades I'd go first for exchange native token. Look for a secured exchange that you like whether old or new. Check them out and If you find which exchange suits you then grab their native token, this what I would do but again your money your decision and your responsibility.
