I still order crowdsourced links in small quantities. Mainly to dilute the purchased links from exchangers. From the pluses so far I see that there are conversions. I recommend ordering crowdfunding here
https://crowdlinks.store/en/, Experienced professionals will place links to your online store on the best forums. So you will have advertising for your store and natural links, so your site will go up in search engines.
I ordered for other sites, as well as on my own site, too.
