The growth prospect is certainly high. But if you asked a similar question, then you are not completely sure. If Im not sure, Ill withdraw the amount that I invested, but only for further investment.
Is a tough decision to make, but I will do the same since I'm not sure if what will be the possible movements that will happen, selling the amount of your initial deposits and used it to other moving coins while holding those assets that left from my wallet and wait if how far ETH will continue to rise, by the way it's your money so it's your call..
