Is there a perfect time that we can say that crypto prices are stable? I don't think so, as long as you know when to buy and sell then you are good.
Thinking its stable is based on individual's judgement, but the nature of the market is volatile and its very unpredictable, so making a good decision is very challeging.
When investors have more money they tend to look where to put it on, I think they are still keeping an eye for cryptocurrency but this time wiser and making sure they are on the right project.
When we say investors, there's many of them but we cant deny the fact that many of the many would also loss their money investing, therefore its too risky as there are winners and losers in this venture.
