2017 was fueled more prominently by scammers like bitconnect and shitcoiners but in 2020 we are watching the real adoption in terms of PayPal and Square investing in bitcoin.
There is no doubt that ICO was at its peak just at the time of the last ATH, but also that it was at that time that it was announced that CME would launch Bitocin futures - which many inexperienced people replaced with BTC ETF. Given that there was no pandemic then and the world has recovered considerably from the economic crisis, many small investors have invested in BTC - as evidenced by millions of newly opened accounts on crypto exchanges.
+1 with this. PayPal moving over to crypto has been a really good welcoming change and Square betting on Bitcoin for long term has increased the confidence over bitcoin by newbie investors. Well these are the primary factors for bitcoin reaching $16k today and I believe we will be watching new highs this year. But what I meant was, these factors alone doesn't bring BTC to touch the $100,000 mark. We should be having real adoption where people buy almost all the basic utilities through bitcoin and for this to happen we need side chains like lightning to take over onchain transactions.
Although some may have thought that BTC could independently conquer fiat, banks, PayPal and everything else - for now it is not possible to exclude all of them and achieve adaptation. Most, however, are not technically so literate that they know more than just turning on a computer and running a browser, and for them, the services offered by PP or banks are an easy entry into the world of Bitcoin. Once they understand the difference between custodial and non-custodial and
"not your keys, not your coins" they will easily switch to proper use.
Right at this moment, after bitcoin touching $16k level I am remembering Hal again. In the mailing list, Hal writes :
Hal has already entered the legend, but I think it is not realistic to expect BTC to become the world's major currency. The world would really have to change drastically to accept this, and we all know that the world’s greatest powers like the USA, China or Russia are very aggressively protecting their national currencies. They are in a way part of the identity of a nation, so that is understandable - and I personally, although I live in the EU, do not consider the Euro desirable and I would like to keep my national currency.
