I think users should be careful. We invest in everything, not just Bitcoin. Always monitor global news. While enjoying the profits, stay alert for legal developments. And as you rightly pointed out, if governments do decide to regulate or control it, the landscape of crypto will change entirely.
We should not come to an end with investment as it gives us freedom to settled our condition in better way but we should be acquitainted of the risk involved in the sort out business. Dependency on investment should be shun as it can make you disappointed anytime.
Always remember that as risk is the integral part of investment so we should be careful about it and whenever we have some beneficial moves then we should accept it otherwise we will fail to take the opportunity after which crying will be our predestined.
If we are saying that we are not taking this sum because we need more then surely you will be unable to take this little sum again as opportunity never exist always.
