Is BOSON free?

I'm curious to know, is the BOSON platform free to use? Are there any hidden costs or fees associated with accessing its services? I've been hearing a lot about its potential in the cryptocurrency and finance industry, but I'm hesitant to jump in if there are significant upfront or ongoing charges. Clarifying this would greatly assist me in making a decision about whether BOSON is a viable option for my needs. Could you elaborate on the financial aspects of using BOSON, including any potential charges or fees?
