damn.... i never thought all that. i only use coinbase and i didn't set up the two factor identification...... now i see if i my phone get stolen i am gonna loose everything. so i will be doing that.
i also don't have any idea about mining, i barely understand cryptocurrency but i got lucky a month ago. i withdraw some sbd from steem to ltc and i couldn't convert it my currency because my trusted website was closed. so i had to wait a week, and my 300$ became more than 550$, i bought sp with those profits......
