SO, this is one of the reasons why SXP price increases significantly. the existence of burning tokens really gives certain influences to the supply, moreover to the price. commonly there will be a certain increase, normally.
But, of course, it will also depend on the fundamentals and also project itself. If they are not considered as shitcoins, they will have more and more chances to grow again and again.
I do't know if there are more burns to be planned or if SXP follows a certain schedule, but if there are more burns planned it makes SXP an attractive investment opportunity. I prefer if the teams announce it in a timely manner that more burns may happen and when they could happen. That way you can deny front running activities by the team itself.
It also increases trust if a burn or a buy back is announced and they execute that plan as per their announcement.
