I haven't sold anything back into fiat since I started in crypto around 8 months ago. I have done a bit of trading to get more ETH and BTC, but most is still in altcoins. Would like to balance out my portfolio a bit more and have a higher percentage of it in the top two, but happy enough holding at the moment. Waiting for some more funds to free up before pushing up my overall investment in crypto, need to take care of other expenses first. Ideally I would like to see the markets hovering for another 6-8 months and then I should be in a position to increase my investments. That's just me though, everyone has different objectives. I don't plan to move any money back into fiat for at least 2 years, and preferably longer.
