New to btc, just set up $100 weekly btc contribution

I used strike and Im wondering if this is a decent way of investing into btc?

I’m 22 and I invest around $5000 a month and realized I need some crypto exposure to maximize gains. I am mostly an index fund holder but I hold a few individual stocks where I see value.

I was wondering if this strategy is good? Currently using strike and I’m wondering if there will be fees when I try to sell in the future?
