# How and on the basis of which you determine a 'ceiling rate'

In preparation, you look at the current price and the historical price development of the crypto coin in question. 

If ***YOUR*** expectation is or you feel that the price of Bitcoin above € X, for example, is a one-off peak, then you do not want the trader to buy back positions if the price rises to that level. You then specify a price ceiling of 3% below as the price ceiling. If your return is now set lower than 3%, the trader will always sell his last buy at such a peak price and you have maximum return. That is the theory behind the ceiling price.
