Crypto investment. The phrase already defines it self. Here your investments are digital, you can start investing on crypto through buying any cryptocurrencies that you want. Most investors started on bitcoin.  Holding is investing.  Trade also does.  But there are also other forms of crypto tradings,  I am not just much familair on them. Trading is buying and selling,  the concept is that,  you will buy at cheap price then you will sell it on an expensive price. That's the rule to win.  But it is not easy as you think.
