It is a great idea it is like saving in a piggy bank for a kid but for us adult it is a great investment we could also teach this kind of things to kids nowadays.
This could really help them in the future I would try this or do it on other crypto as well save small money in crypto and hold it till you need it,
Instead of wasting my money on vices why not put it in crypto it would help me and my family in the long run.
