as all people said .. you can invest in growing altcoins like XRP, LTC ..as they growing too fast more than BTC
XRP is growing like XEM which is also cheap. A smart investor should start collecting some of these before they fly up and you would have to spend thousands to get thousands of these tokens. Early adopters and always bagging.
This is the new age of investments, joining now is much better than joining later, not only Ripple and NEM, many blockchain projects have the potential to grow in value by the time, I have recently invested in Chronobank and Iconomi, and waiting for Matchpool to join exchanges, so that I can buy some GUP.
XRP and NEM are very cheap and buying 50 or 100 coins are not a big investment and these coins have a good potential,
Chronobank I see that the price quite stable and can expect growth but is too expensive for all I care
Iconomi price is also stable and is not too expensive at the moment, I'm going to explore that coin
