It is never a good idea giving this kind of advice. Luckily I changed my SBD now, for 0.50c exactly. That is a huge difference.
Were you hoping Steem would go up in value? I saw no indications it would do so, which makes me wonder where you got your info from.
Oh well, as they say, it is all a gamble, sometimes we win, but usually we lose.
It's never a good idea to give any advice because someone always disagrees.
I will always trade SBD to Steem when I see I will get a lot more Steem for my money. Is it ever the perfect time? Not likely, but in the long term it will pay off.
