Investing is part of failure, then I suggest to all do not lose hope if your expectations are come true, so patience is important and wait for next chance to earn profits by holding altcoins.
How long we should be waiting? I know it will have that advantage but it is quite no good to be in patient all the time. We don't to be stuck and wasted a lot of time just to keep in waiting, the market moves slowly and so it takes most probably a year before we will on the ATH again. And I never feel good for that long. Better to have some investment right now and even we gain small amount but it is good enough rather than of wasting our time for nothing.
What are you talking about? Bitcoin and crypto is only 10 years old. Have you been waiting for 10 years? If you waited from the start to 2017 it is only 7 years long. If you are like the people complaining like you are now, then you probably bought at 2018. So maximum time for you is just one year. If you cannot even be patient for 2 or 3 years then it is time to forget crypto.
