For as low as 8 euros, I can have a decent, secure web hosting provider with a free domain name to try an idea of mine for a month. If I spend only 8 euros on hosting and domain I’m left with more money and freedom to spend on advertising. GoDaddy offers a monthly payment plan on Managed WordPress Basic which is approximately only 8 euros for one month domain and hosting

• Free SSL from cloudflare
• Free Domain Name
• 8 euros hosting
• 1 month low risk, high value

If I focus on finding a gap and spend 8 euros only for domain and hosting, and 140 euros on google advertising. Is it possible? I can still focus on my goal and spend the rest of my time on researching.
I have committed though to another goal but this realization will come handy at a later stage.
