Bitcoins will need to have all its scaling issues resolved as I don't see the world yet completely involved in the crypto usage.
Once we see it being used widely and at a global level, do you see any possibility for Bitcoins to scale the number of transactions that will occur over the network? I think that there should be some special organizations to spread awareness through all the crypto-related education among youngsters and make them more confident about the crypto world. Bitcoins, if utilized properly and if the future generation will be guided truly, can make fortunes for them once they learn the patience, the power of HODL.
