Gold and silver are considered by many to fit the bill. Held value for many thousands of years, it is likely that has not changed. IMHO get some AG, AU, then some BTC and LTC, maybe feathercoin too. It pays not to keep all your eggs in one basket!
The problem with Gold and Silver is there's very small growth potential and they're also very likely to be over-valued right now (according to the sources I read, anyway).
Altcoins, however, may be extremely under-valued now, so there's a huge growth potential.
Say you bought 10,000 PPC for 30 BTC (0.0029 BTC/PPC) which is $4,300 today. There are 2 x 2 possible scenarios:
1) PPC goes up, BTC goes up (big win)
2) PPC goes up, BTC goes down or stays (win)
3) PPC goes down or stays, BTC grows (win)
4) PPC goes down or stays, BTC goes down or stays (no change or loss)In 3 out of 4 scenarios, you win!Let's take the best possible scenario: PPC goes up 10x since it's so cheap today and BTC goes up 2x (none of this is science fiction, as we've seen much higher growth in the past).
Then your $4,300 that you've invested have become $4,300 x 10 x 2 = $86,000!. Not bad, eh?
Obviously it's a no-brainer to invest in alt cryptos. You just have to do your research and find out which ones have the future (active dev team, proven history of stable existence, acceptance, etc).
