if 2019 will not be the year for btc than definitely 2020 will be there. because i am sure about the future of btc and the blockchain technology. i will keep my portfolio holding.
Since the cryptocurrency market is now declining, I dont expect much growth this year. It would be good if the growth of altcoins began, then I would start to move to Bitcoin. I dont think that 2019 will be a bitcoin year, so now pay attention to altcoins. This is temporary, now the market will be restored and the cryptavalue will grow well.
