I have $100,000 to invest but want to safely double it in a year. Any suggestions?
Buy stuff to ebay then sell it to amazon? I have saw many tuts in google about buying stuff in ebay then it will sell on amazon, I think it's a good investment if you're good in buying/selling or you better to start own business like cafe or restaurant that nearby on your house. ;-D
Or he can try to invest in bitcoin, although its litle bit risky but the chance to get profit is bigger. If he still worry, just take some part of that money then invest it in bitcoin. If he get profit he can decide to put all of those money in it.
