How can we solve it? and what is the good advice that you can help in this problem.
We have to be aware that every investment has risk, that means if you invest your money in crypto it doesnt guarantee a 100% profit. You have to be prepared for the outcome and make sure your capital is a spare money so it wont hurt you that much if something unexpected happened.
This is the problem of some of us, we already count the potential profit we can take in our investment but the reality is the opposite of what we anticipate. Well in times the value of our coins are declining the best thing that we can do is to hodl and dont think about the current situation of the market for a while.
I often say to my friends to not cut your losses and continue to hodl, wait for the value to increase then sell. There's no pain in waiting so better to do so because its one of the effective way to recover your capital if you're not that patient to wait for bull run.
