if I spend it to an exchange will have any problem
As said, if you want to avoid problems, just move your Bitcoins to another address under your control before playing with the other forks.
Or, if you are unsure and not too experienced with wallets, just ask somebody with good reputation (like LoyceV) do all this for you (probably for a fee).
Plus, if you have a significant amount of bitcoins you still want to hold, consider getting yourself a hardware wallet, get used with it, and only afterwards start moving coins around (preferably towards your hardware wallet).
