To all those who are experiencing (repeated) blockchain sync issues: first backup your wallets, then run a filesystem check on the volumes containing them. Then a thorough (surface) check on the relevant physical hard-drive. Then make sure your power is stable... if not, buy an UPS. The speed of your internet conection is influencing only the time necessary to sync.
Have fun, buy what and when you can, stake and create

L.E. test your RAM too... memtest86+ is free and open-source. Also, I assumed your systems are malware-free
