You bring up some very valid point. However, I totally disagree with you about this even being anything close to a bubble, yet.

Sure you can point to certain coins and say they are bubble...perhaps even Bitcoin. That said, the underlying technology, which is what these coins represent is in its' infancy. The upside in all of this is tremendous. Does that mean every coin will go to the moon? No. As you said, choose wisely....there is a lot of garbage out there. Many of the platforms these coins represent wont even get off the ground.

Prudent financial management is always welcomes. Nevertheless, many like to throw the term bubble around simply because something went up in a quick period of time. I bought Tsla at the "bubble" price of $240 and have ridden it up to $380 and now it sits at $350...of course many are still calling it a bubble.
