Before it's too late?
Nobody should be worried about that right now. We've got lots of time to accumulate for the next bubble. The recent crash pushed any possibility of a bull market back by many months. Now the market needs to absorb all the new supply at these levels (supply from bagholders at $6,000+) before a reversal and uptrend will take place. My speculation is that we'll enter a bull market in 2020 and the next parabolic run will occur in 2021.
Some like to save "in socks", others like to save through long-term investments in real estate or in gold, and others like to risky saving by investing in cryptocurrencies. Everyone decides what he want to do with his savings. I think that the prices of all cryptocurrencies in 2018 have fallen so much that the risk of loss has dropped to a minimum. So if you decide to invest, this is probably the best moment.
