When we think of the problems associated with Bitcoin most of us think volatility, profit and lost, pairings via fiat. Crypto is still a tabooed topic to approximately 95 % of the world.
I picture crypto holders presently are small groups like us on steemit preaching and posting to our own-selves with the words and topics bouncing of the walls and reaching and few(slow and steady growth is good).
When I read post and watch videos 90% of those who hold crypto just want more fiat. Can anyone really imagine a day that 50 bitcoin will worth 50 bitcoin and paying your taxes, school fees and purchasing other necessities only using crypto.
There is a cashless payment service happening right now using your cellular phone Its also peer to peer and it not decentralize. My conclusion is the way we see Bitcoin presently is mental and I think it will take several generations to adopt this as a daily spendable currency.
