Is it SMM niche ? If so, then NOWADAYS the first aspect about convincing potential buyers, would refer to the payment method(s) that a buyer would use to pay for SMM services.
I will explain it :-
When buying SMM services, buyers prefer to pay with PayPal. NOWADAYS, PayPal is suspending PayPal accounts of sellers who are accepting payments for SMM services.
The reason why Paypal is suspending the same is because PayPal considers SMM services as counterfeit (violates PayPal's T&C's). The reason why Paypal considers SMM services as counterfeit is because some or many SMM service sellers use bots / botted social media accounts.
But, many potential buyers still say "I have only PayPal, I can pay only with PayPal" (ofcourse they are lying). Now, the good thing is that NOWADAYS PayPal is ALSO suspending PayPal accounts that are used for BUYING SMM services, because PayPal considers SMM services as counterfeit (violates PayPal's T&C's).
Why am I mentioning all this ? Because, as a seller of SMM services, when you will encounter potential buyers who say "I can only pay with PayPal", you now have a legit, real & true reason to discourage them from buying SMM services using PayPal, by explaining to them that EVEN FOR BUYING SMM services, PayPal is NOWADAYS suspending PayPal accounts.
Hence, BOTH the buyer and seller can NOWADAYS avoid any "accidents" caused by PayPal, which NOWADAYS hurts both parties : the seller AND the buyer (for SMM services).
Therefore, NOWADAYS, when it comes to selling SMM services, the above important aspect needs to be kept in mind regarding accepting payments for SMM services.
Many sellers and buyers NOWADAYS have realized that PayPal causes high level "accidents" when it comes to selling AND buying of many non-physical virtual digital products and services and therefore such sellers AND buyers are NOWADAYS happily embracing crypto.
DISCLAIMER : About PayPal considering SMM services as counterfeit, I am NOT responsible, as I do not own PayPal (nor does my dad own PayPal). I have just mentioned the truth, fact & reality that PayPal considers SMM services as counterfeit. I have absolutely no control over PayPal's T&C's in any manner at all whatsoever.
