So I have taken notice of this "coinbase effect" and I really believe that it is true. I think that people are downloading coinbase, seeing how high BTC is, and deciding to invest into LTC and ETH instead. I am NOT saying that these coins will pass BTC in any way, but I do think that LTC and ETH will be in the 4-10 thousands next year for sure. I made a video with my full predictions and thoughts, please check it out and let me know what you think! Thanks
