I go with you that the volatility will go down as it becomes a larger part of the economy. BUT I am not sure which cryptocurrency is #1 when the date Comes.... Bitcoin? Perhaps if LN works perfect. But that's another Story...
For me the volatility and the fact you can send your hole money to the Nirvana if you have a little mistake in the adress are the most big Problems in cryptocurrencies... What are you thinking, guys?
