If you start with 10-year statistics, then any of the top coins of the crypto-currency market has a rise and fall in quotations several times a year, which is enough to make a profit. Take for example DigiByte - during 2017-2018, its cost has changed more 4 times, synchronously alternating the rise and fall. You just need to carefully select the coin for trading and you will easily adapt to its fluctuations throughout the year and be able to make money on it!
I think you know the answer, no one can tell you the time. But I hope it will be very soon. If new investors gather in the market then the market will rise faster.
