if you have 5 eth, you better hold it for as long as possible. Next year the price of Etherum is more expensive than now.
nowadays it is difficult to find a good ico because the price of bitcoin continues to fall
Too long to wait, too, is not worth it. I would wait for the next price increase, maybe it will not be as strong as the previous one, and perhaps it will be much stronger. In any case in the future there will be more pleasant investment opportunities for your ethereum.
