With the recent spike in Bitcoin transaction fee, it's evident that these fluctuations are significantly impacting the adoption rate of Bitcoin.
There's no how Bitcoin transaction fee can be a detriments to the adoption of this digital currency, people are not focused on this at first, what they are after is first to have an alternative to the way they handled their financial economy, that change is what they wanted to realized first, increased transaction fee is something that already have alternative to pay more lesser than than higher.
While there has been a temporary reduction in fees, the underlying issues leading to the initial spike remain unresolved, raising concerns about the sustainability of the current fee levels.
That shouldn't be a problem as long as it has nothing to do with affecting the bitcoin network nodes, we may anticipate to see what this new year may bring if the developers conclude on arriving at something new to solve the problem, because bitcoin users are the ones being affected.
