That's actually a risk that we can decided on whether we'll take it or not. Just like stocks, cryptos can be volatile -- even way volatile for some. Personally, what I do is to slowly convert SBD to STEEM regardless. At least, by doing so I can smoothen out the price. Although, my goal is to really accumulate STEEM Power.
If your goal is to "trade" and take short-term gains, the strategy will be more complex -- which I lack knowledge thereof.
Thank you for sharing your experience and strategy.
