Smarkets New Customer Offers Reviewed
Even though Smarkets was founded in 2008, it is generally not considered to be among the best in the UK. However, this mainly has to do with its nature - being a sportsbook exchange - and the bookie can thus be forgiven. Indeed, the site ranks second when looking at betting exchange sites, and there is an okay welcome offer as well.
📈 Betting exchange Welcome Offer - COMMFREE
The welcome offer at Smarkets allows new customers to trade with zero commission fees in the first 60 days. Indeed, one of the big flaws of betting on any exchange is the commissions charged, and this can be offputting for any potential customers.
This, therefore, is why we like this offer so much as it effectively makes the site like a normal betting site - even if they also charge through the betting margins. In any case, the welcome offer makes the betting exchange experience a bit less daunting in the early stages and that is good news in our book.
