We have seen a massive surge in bitcoin price since we enter into 2021 almost same, trend happen in 2017-2018, only there is a big difference, in a situation today before, I think it was just a pump, but there is a big difference in this year's price rally things that are notable are the following, the influence of Elon musk, Visa considers to enter to cryptocurrency, Paypal decided to open to cryptocurrency, banks, and other institutions open its door to the possibility of using it, suddenly this year pandemic helps cryptocurrency get into the spotlight in the positive note, although there is still negativity being thrown, I think most institution study it and they realize the possibilities and important of blockchain overall.
it may be true that the surge in bitcoin last year was almost the same as in 2017-2018, but there is something that distinguishes it is bitcoin has not corrected continues to decline this year, hopefully it will not happen and it will continue to increase.
The external role in bitcoin is indeed very thick since last year and it was unavoidable, since @elonmusk bought bitcoin which resulted in a sharp increase and added to other factors.
I hope what you say can come true because positive things happen because it could be that blockchain will be an alternative for further developments to be used, we are waiting for that because of course this is a good thing.
