Is it okay to use Let's Encrypt for telegram bot?

Question

Digital certificates

I bought a domain for my bot a year ago and got an SSL certificate as a gift, now I get a reminder that I need to renew it, and this pleasure costs 1500 rubles. In fact, I think I can basically use Let's Encrypt and not pay anything? What could be the downside? What could be the reasons to pay for a certificate, instead of let's encrypt in the case of a Telegram bot? (If possible, then describe what problems there may be in the case of other sites, most likely some kind of security hole)

Answer 1

I think it's quite possible. The difference between certificates is only in the level of trust. Will work. Reasons to buy paid, even the most dishman - I don’t see if LE is satisfied with the behavior.
