Buy XEON by Dec 26, 2028.

I want to invest €10,000 in XEON. My question is whether I can add a large amount of money, like €3,000 per month for 3 years, into XEON, and then sell everything at the end of those 3 years, using it mainly as a way to park cash and accumulate interest. I’m not looking for high growth, just to accumulate interest with low risk and high liquidity. Another question: which broker would you recommend the most for this strategy?
