I think selling everything for Crypto is not a good thing, especially the market conditions are dropping so I suggest being patient and waiting for the right time to invest in Crypto, rest assured that crypto's future will continue to improve.
This is a better time to invest as much as you can or your ability will payoff intensively in high market if you buy more in numbers. Do not affect your other works only for this investment but those are important too as we know about management of everything which will work out only if you keep some amount for investment and some for other life works so that you will not face with any inconvenience.
ofcourse for living a better life one must know how to manage everything in life, if one loses his profit it does not mean that he has to quit all the things like trading and investment, he should learn how to deal with his profit and how to deal with his money. yeah the First thing is that we should not trade with whole amount there is alot of risks and the second thing is always be careful of the timings when to you buy and when to sell because it plays a major role in profit making and losing.
