Nicely said. I think that 2019 will be a great year for crypto because all of those scammy projects, that just took the investors money and haven't done anything useful with it are going to be forgotten and slowly die. So yeah 2019 is a long awaited year where real projects will shine and make a new momentum for mass adoption of cryptocurrencies.
