I (and maybe everyone too) have learned a lesson with SBD: HODL it as much as possible and wait for the next (abnormal) pump. SBD peaked at $22 last May, and here we are 6 months later with another massive pump. It's fair to say nobody could have anticipated another surge like that until today, thanks to those Korean exchanges. Who knows what could happen in another 6 months, or less!
And that's not all! I've been paying close attention to its price on Bittrex for a few months, and very often it got a weekly pump. For example, it would surge to $2-3 in the space of a few minutes! If you're lucky to have placed a sell order (which I did a couple of times), then you would get a nice little quick weekly profit!!!
As for STEEM, having it stored in Steem Power is the best incentive to hold it for the long term. After all, we NEED Steep Power to transact and increase our stake/influence. DASH and Ethereum were cheap last year, below $10, but once they got their recognition, they skyrocketed. Everyone who missed on those look back and slap themselves: Why oh why didn't I get some?
I think STEEM is the perfect opportunity, I can't wait to see its value in one year. It too is bound for a glorious moment. Almost every coin and altcoin had their 10x surges (whether by a pump or by slower growth). STEEM is no different. Get it now while it's still cheap. And finally, investors seek price stability. STEEM price remained relatively stable despite all the market volatility since this summer. Major coins got up and stayed up, shitcoins got pumped and dumped into oblivion, yet STEEM is still here unbudged! THIS is a good sign for the future. Things can only go up from this point on.
STEEM/USDT pair in most exchanges will provide more stability and more trading opportunity. LTC, DASH, XMR, and most top coins have USDT pair in top exchanges. For example, one did put a buy order in BTC, BTC fell 25% and STEEM fell 10% against BTC, therefore, it fell against USDT by 32.5%. It is hard to trade inter-day with STEEM against BTC. Hopefully, STEEM will be added to top exchanges and traded against USD sooner than later.
