Here are some important points I have been debating lately with crypto aware and noobs alike.
1) The dot com bubble had much more funds like trillions at play we are not even near that. 2) The dot com bubble took down people that invested in bubblyboubles.com and not in amazon or cisco or google or microsoft or adobe.
So don't buy megacoin, buy something that has good tech (and don't expect tips in this post).
3) even after the dot com bubble burst, internet and .coms are still here and actually booming. So yes if you buy a shittycoin today and tomorrow you read some news panic and sell you are in your own personal dot com bubble.
