Hmmmm, you use to be able to buy a nice used rolex from a needy individual and flip it..but not for double.
Hmmm, it depended on at least a 6 month venture..and it still wasn't sure. Buy gas futures in summer betting on winter use being in high demand. But that takes time...
Hmmmm, you use to be able to buy WalMart stock in May-July...holding for December, hoping for a good spending year...maybe even a split or rollover...but double money would be hard and WM stock is stable...not like back in the 1980's.
Hmmm..CD, Treasury Bonds and Notes, Mutual Funds...take longer than a month to build up.
Hmmmm, land takes waaay to long AND you definitely have to buy low and try to sell as high as possible. I did this a few times...but it took me about 20 years for it to double+..so.
Drilling a gas or oil well..to get full production and royalties paid takes time...
Cattle...unless you know they're going up..like skyrocket soon...
Hmmmm, gold, silver, platinum...not in this economy. S&P500..nope.
Banking stocks, oil and gas company stocks....nope.
Unless you had inside information...I give or it hasn't hit my mind...yet..to tell you.
Hmmmmm...betting..horses, craps, blackjack. ...and such. You have to look at your initial bet -versus-odds...even then you may have to press your bet and keep doing that for ..who knows how long...plus LUCK..in not losing any money.
Chicken fighting. .uhh..um...I mean..show fowl events. Do you trust the bookie/placing the bet? Do you trust that you'll receive your return?
Is the fight..uh..um...fowl show..real or fixed. Will the handler release the rooster at the right moment?
Double your money in a month and it's legit?? I'd like to know that one also.
Fastest money I ever made in my life was on scrap iron. If you do your homework and know your metals its still not hard to more than double your money and not wait a month to do it. I was going to post some actual facts on metal I bought and the price I received for it but chickened out cause I'm not sure who's reading....
In days gone by I coulda more than quadrupled 10 grand in a week much less a month, now days I'm not the same person. If I had 10 grand to piss away I would pay down the principal on my house.
It would take more than a month. Buy good quality hay in the spring and summer, tarp it down, sell it in the Winter, make even more money if you haul it to Texas and sell it there.
Make sure you wear the cloths you are wearing in your picture when you sell it in Texas.
There's no sure thing. Or everyone would be double ing their money's. Learn to count cards. Dbl deck at T bird casino is pretty easy. At a $100 a hand you could play a while and one good shoe and it could be done.
