i'm also wondering if this phone wallet's are safe...out there are bad people who are using new technique's how to get money for no effort from hard working people...i think if they can scan credit card and phones...they can do this to...it's just mather of time...but on the other side this tehnology is very complex...who knows...

Is there some link with all this explenations with all this concepts for noob's like i am...i can't find it on forum...
tnx for help

My friend was mining for bitcoin with antminer's...but the dificulty went so up it wasn't profitable no more...so he bought GPU's and started making money again...he told me several times to get in "the bussines" but i didn't had the money at the time...in the end of may this year i got my first GPU miner and the profit was super...i got my investmen back in 3 months but then went down...prices of coin's were droping hard...sometimes i did not even cover my electricity cost...with today's price i'm making about 60$ profit with 9 GPU's...in my country electricty is very expencive...so this is my main problem...i'm searching how to reduce elec. cost...

 "whattomine.com"  is very good for getting info about which coin to mine, what is the profit,...

i agree...my friend made nice amout of cash for selling them at the right time...and he is still in the "onion game"...waiting for the right price again 

for me "the game" just started few days ago...because i didn't listen to his advice...
so i hope i Will get some "profit" in the future...

What happened  ...this was my first coin in a bigger quantity...had a big hope to get some $$$  ...maybe next year will get better...maybe someone will take it over and make it alive again
