It will surely have good impact on crypto market in general but some are saying it will outrival bitcoin which is very hard to believe for me ,globalcoin will do fine no doubt but can't rival bitcoin
It cannot rival Bitcoin, I agree with that, I share the same perspective.
However, what makes you think that it will have a good impact on the crypto market in general? Because it inevitably raises awareness for cryptotechnology & DeFi?
Facebook has quite strong impact in a modern day society so launching a project will definitely raise awareness and could really educate the public about cryptocurrencies. It can clear up misconceptions about the technology and the industry. Personally speaking, I encountered some ignorant relatives who absolutely know nothing about crypto but talks about bitcoin like its a ponzi scheme or something. Really though, this can help remake the reputation of the whole crypto industry.
