You lock in your coins to the network and earn interest on your investment. Much like a savings account through a bank. Except the interest on crypto is much more than any other traditional bank or interest yields. THEN, there is DOT and crowdloans. An opportunity to lock in your DOT tokens or ksm to support projects on the network. You get your tokens back at the end of the auction, while earning coins from the project you support. You just have to decide what is best for you personally.
