I have personally invested and gained form Alt coins. Bitcoin or Litecoin have limitations in many aspects as far as low risk capacity but high gain dreaming investors are concerned.
Do you know that the two coins that you mentioned don't have that much risk to it as an investment because the price s of those coins have somewhat of a stability beyond a certain price range.
Litecoin is one of the coin that I would invest in nowadays because the developer for that coin came back and stated that he is now working on Litecoin. Some people are wondering when Ltc was going to get popular, so I am guessing that this is it. This ia the right time and I am right with my speculation.
