An investment in SD is a safe bet 
it is absolutely a safe way to get coins to grow, much better than having them laying around in your wallet.
we can all agree that SD is safe and they will not steal users coins, and when you do not trade the coin, they can just as well be invested in SD and grow.
SD have a lot of their money in cold storage, there are often lots of complaints on here when people try to withdraw large amounts of BTC and can't because the online pot os dry - so its quite safe from hackers too, I think only a small amount of BTC would be taken - unless it were an inside job or the hacker somehow managed to access the cold wallet.
yes, and if the hot wallet gets hacked it's SD who loses the coins not the users.
I'd forgot about that part of the policy. SD is looking like a pretty safe investment bet (in comparison with others in Bitcoin) - its been running for a few years and I didn't see any complaints of money being stolen yet, other than in the old days before login when people used to foolishly post their URL on here
certainly a safe investment, although I do not have a lot of coins, I'm still satisfied with the return.
