Yes. That's a perfect piece of wisdom. This is perfect opportunity to invest in crypto's. But if someone had already bought crypto sometime earlier then holding is the best option fro him instead of selling and taking some huge losses. Crypto's market has always been so volatile and specially now because of this Segwit hype. Everyone is selling their shares that;s why market is falling down. Now a wise investor will definitely purchase new investment while a fool keeps on shorting his shares.
But because of your advice, most of the investors who follows you, thankfully would hold thier shares. You have given a great insight about this whole crypto fall. Thanks a lot @exyle
