Gamble or Invest IMO 
i think invest and gamble is same here, because both need very big risk, 95% of investment sites will become scams , until you get back the amount you have invested, while gambling you can get rich fast or lose everything, while investing lose it will happend slowly
yes you are right. invest and gambling the same having a big risk. but there is an investment with little risk, such as lending and mining. I've been doing this for a long time and is still safe till now. but for lending you should really pick people who really has reliable.
are you talking about cloud mining? most of all them threw me out and others have different problems, witch are very uncomfortable for using and about lending, i have not tried yet, but i will wish to try it, if i found trusted person, whom i can lend btc
yes I am talking about Cloud Mining. there are several cloud mining that still legit, such as bit-x and hashnest.
I am sure you can get a good profit on lending if you have found some people who trusted
ya, bit-x is really good and trusted,but ROI is very slow, but hashnest? i have bought 100gh s7, now price is so low, that i need to sell 200 gh to get my investment back, price is falling down every day, i think its impossible to get ROI from them, also i cannot withdrew my earning, i have google authentication problem more then 3 week and no one is not helping, i have opened many tickets, have written here and on bitmain forum many posts, email them also, tried contact from skype, but no answer. i dont know what to do now:(
