Can buy SYSCOIN, but not invest, just use it.
Now posible invest only in BITCOIN, all altcoins extrimly overpriced.
ETH,trust me ..i guess ETH will take place of BTC, if BTC don't update
ETH or Ethereum is a good altcoins to buy, but I was not agree that Ethereum was replaced bitcoin on the top. Maybe it was happen in the future but I think it was a long journey before it happen. Because compared the price of both altcoins it was large difference.
