"from a guy who has seen MT GOX disaster, Paycoin, LTCGear, Cryptsy"

You have to remember that the times have changed, also within cryptocurrencies. Acceleration rates of new startups are higher, block-chain technology is reaching more and more people on a daily basis. And with Steemit being its own company, there won't be much room for "scandals" and with the investment opportunities like Steem Power it also takes away a lot of the possibility and profitability for hackers to try and get a hold of your accounts and considering the action that is taken against them makes it even more dangerous.

But with time it will become more stable, secure and amazing. Remember the beta text under steemit. :)

Good post in general though! I am inviting a lot of real life friends to steemit as well and helping them out to create their wallets, save their keys properly and make their introduction post. Everyone is amazed by it so far and can't believe something like this exists.
