There are a number of available options in the market if you want to choose between digital assets having low value. These include Zcash, Ethereum and Litecoin with many more that could be found easily on the web. So you have to do a two-step task that is first buy them with your current money and then wait for the prices to increase and in my view this would me much time taking and a lot of patience would be required so it is better to use Btcs instead of these lower market caps.
