Temporary investment you say
 Though I haven't heard of that one but if you're looking for a good short term alt to invest in you need to find a project that's just coming up, Go through the AMA and Initial coin offering. With this you can ask a lot you need to know about the project on AMA and buy at cheaper rate at presale.
If the project eventually has a strong back up and support after the listing am sure the value will increase and you'll surely make a fortune. Or Bette still you can go to binance to buy any small alt like trx, xrp,doge etc. Within 2 months your return will be huge
