You have already gain enough, so it's up to you what you wanna do. As it is your investment fund and not for spending, so there is no need to worry about selling now. As more and more investors are pouring in, so I believe there is high possibility that bitcoin will make more gains in near future. Over the years, bitcoin has been the best investment sector as other sectors have been struggling and Covid - 19 have also increased investors woes. There is also general fear that if some governments start banning bitcoin then it would crash again. In spite of that it wouldn't be a bad idea to keep some bitcoin in the wallet. Who knows if luck favors then it would hit new peak again.
