The best and wise thing to do is save your bitcoins and altcoins until you get a huge profits and benefits on it. If you already need it very much then go sell for it but if you don't need it then hold and wait until the right time comes so you will gain a lot of money for it. If you do this then you are right because this is the only way to do with your savings.
I hope that you're right. How can you be so sure about it though? I don't think it's wise to go around giving people this advice. What if you're wrong? I hope Bitcoin with keep growing. I think it will. I think a lot of altcoins will keep growing too. There's no guarantee of this though. I'm sure that many altcoins will fail. How can you account for that? What if this guy has his money in altcoins that will fail? It wouldn't be to smart to HODL then would it?
