I think noone will pay attention on technologies and etc, because noone have payed already. There were enought coins will great technology in 2018 and all they are dumped
It is because of the investors involved in the cryptocurrencies as they are not the stronger investors and traders. If they will be stronger to their coins and will not let them to dump then the price will not dump and will grow. They also need to promote their coins and have to invite more people to the cryptocurrencies to invest in them.
