Your best bet for coins that could go to 10-20x, are low valued but high volume coins. Mint and Linda are currently 55 and 11 sats respectively, but they are in the top traded list in exchanges like cryptopia.
And you need to say the truth, it is pretty difficult to look for an altcoin that will make x10 or x15, the guy who created this thread is very, very optimistic.
The only way in that you can easily make that kind of profits is if you invest in one of those coins who are under the top 300 of coinmarketcap, with less than 20 millions of 30 millions of dollars on their total marketcap.
otherwise, you are just going to invest in overvalued coins who are not probably going to make that kind of returns.
I know its a gamble, but it is worth it. I dont have kids or some overpriced blonde bimbo wife who has been pounded out many times to take care of So this is a good time in my life to take these chances. Plus I am trying to recoup some money I lost thanks to bad advice from some garbage ass dude who advised me to invest in some scam thing called a HYIP. Never again will I get scammed like that .
I know its possible. Look at Russiancoin today. RC seems like overnight it blew up. A few coins I hold know have went up about ten times from where they startd.
