Thanks a lot for sharing this post very informative.I personally feel we may not be in a bubble yet but while the transaction fees are high bitcoin may never really be used.I recently introduced my friend to cryptos and he is really fed up with fees so i had to educate him and told him to always use LTC for transactions.I really think the community needs to do as much as they can to welcome new users so they don't make the same mistakes that we once made.
