There are cryptocurrencies whose projects are basically startups, because they have platforms for blockchain services and applications.
Take a look in the top coins on the coinmarketcap site and look for projects with more potential to grow.
Investing bitcoin on different crypto projects is quite good in my own experience and sometimes it can make your bitcoin grows up to tenfold.
You need to find the right project to invest. If you invested in the Etheruem in 2014 and hold until now, it is good profit.
