I missed the opportunity to invest in Bitcoin when it was under $500, and also missed the opportunity to invest in Ethereum. Now I see that BTC, ETH, and basically all cryptocurrencies are going down since 12-14th of June 2017, so I've deposited some money on Coinbase ready to invest in any of them. But the price is still dropping day by day, and looking at the charts, I'm not sure what to do, and I have a few questions: Can anyone guess or tell me when would be the best time to invest (when will the price go up again and what factors have to happen for this)? In December 2013, when BTC hit $1000, the bubble popped, and more than 3 years had to pass to reach $1000 again, and I'm afraid that the same is going on right now. Can someone prove me wrong? Also when the time comes, which one is a better choice: BTC / ETH / or something else?
