I bought back in at about $1.95 per Steem Dollar a few weeks ago (fluctuations have been interesting since then). All in all, I view it like anything - buy what you can afford and sell what you need.
The only reason people freak out about the value of crypto is because it is so easy to check on many platforms. The same would be a freak out point for fiat currencies if their value was as easily checked up on regularly. The media doesn't help though, whenever there is a few hundred dollar drop in Bitcoin there are plenty of sites crying "crash" but where are they when there is a $1,000 jump in an hour? They are usually giving pre-rolled replies along the lines of "that is not news" or "it will come down". Of course it will come down - just like it will go back up, yet they don't see that as news worthy to cover.
The "crash" so to speak was just an opportunity to buy back in and enjoy the small fluctuations at this level. Sure, they are more daring and nerve racking when the value is over $10 and we see fluctuations of $2 to $4 versus $0.20 to $0.50 but still fun nonetheless.
As with anything, don't invest more than you can afford to lose. It is an old saying bu it is true. Also, don't beat yourself up because you missed a wave, bide your time and enjoy the ride as another wave is forming out in the crypto ocean right now.
