Llevan varios dias con los mercados LTC y DOGE cerrados. Sin más explicaciones

Knowing the "mechanics" needed to buy and sell Bitcoin is not enough, we are talking money here. I know  how to buy (via blockchain.info) and send to whoever sends me one of those 30 character key to receive it. So far so good if it was an eMail account for instance (no risk of loosing money), I can send and receive eMail happily without knowing the internet technology behind (Http,Tcp/ip, packet..) I just need to know how to register, choose a password and login.  
I can´t find anywhere in the www a good tutorial (English or Spanish) to make me clear what is the diffence between a "Wallet address" and a "Bitcoin address" (not how to use them, I insist)  
I find it astonishing how many people are trading in the net wihout a basic tech knowlege.

Of course I am a heavy user of on line banking (money) with little knowlege of the H/W and S/W that makes this magic possible, let alone the corporate and goverment policies and  potentiality to meddle with it.
This is different thow (may be shoudent be?) these bussiness are long, time and massive use proven, its use has extended so wide and deep that our society depends on it, so we must trust.
This is not yet the case for any blockchain applications and as long as the general public is not educated, we will continue in this Catch-22 situation: No tech knowlege-no trust-no massive use-no knowlege..
