50 different coins...
You know, there is a type of bubble in Crypto, but its not Bitcoin itself, but rather what is happening with the Altcoin market in general.
Take for example, there are about 12 Altcoins specifically targeting the "Weed industry":
Potcoin, MarijuanaCoin, DopeCoin, CannabisCoin, HempCoin, etc
Yes all those coins are competing as "niche coins" for a specific industry.
Then there is Titcoin, Yes, you read that right, Titcoin. Aiming to be the "coin of choice" for the Adult industry:
titcoin - Google Search
Then there is the infamous Coinye coin, the Coin that Kanye West sued to oblivion:
Kanye West Sues Coinye Altcoin into Oblivion
The bubble in Crypto is that there are wayy to many altcoins that in reality are worthless / unnecessary.
