@whatsup,
"but it sure feels unnaturally fast and that gives me reason to remain cautious."
Yeah I have the same feeling! LTC made a rocket to moon but for how long? ETH, BTC networks are slow and progressing millions and billions of transactions by 3 transac to 5 transac per second! Then investors made a wrong choice again by LTC :D
SBD is not at a correction, it might rise more, for me it should be at $10 and hope it might PEG at $10 and investors are still not understand the value of STEEM/SBD and BTS! Hope they will, don't know how long it will take!
Anyway for me STEEM is the best choice! Wish to see it at $4 margin soon and then rise rise rise!

Cheers~
