I'm a noob crypto investor with a modest portfolio on Coinbase and I noticed that BTC, ETH and even Litecoin seem to move in lock-step. The graph ebbs/flows are nearly identical and that makes me wonder:
1. Are the dips correlated to Coinbase outages? There were a number of performance issues that we're fixed as a part of scheduled/unscheduled maintenance
2. Is coin diversification amongst the major ones even a thing? I mean what's the point of variety if they're all going to rise and fall together?
I could be off about this but just wanted to see if this resonates with other ppls observations.
Also do not keep your coins on an exchange like coinbase, get a crypto currency wallet and store in there.
