Are you in Crypto yet?  You should be!  I'm thinking of giving Crypto to people for Christmas and that got me thinking.  Crypto would be an excellent way to save for retirement, for a childs college or their well being in general. What could that do for them? This will blow you away! This is simply Buying and Holding, what I've recommended as the easiest way to do it.
Had you invested JUST $100 in any of the top coins a year ago the value of it now will blow your mind!  Take a look       
     Coin                    1 yr             5 yrs
Bitcoin (BTC)           $336,          $8052
Ethereum (ETH)      $880,          $44,000
Solana (SOL)           $10,142       NA
Terra (LUNA)           $13,600       NA
Want to know what $1000 would be worth now?  Just add a 0 to the end of it.  It's not uncommon to invest $1000 and in two years it be worth $1 million! 
So you see, you could very likely invest a little now for a child or grandchild and they would never have to worry about finances the rest of their lives!
