It is very harmful to NLG that its success depends on using a 3rd party processor to make transactions. This is my primary concern and has been since NLG started having extended block times.
3rd party payment processors only apply selling pressure to a coin since they carry the fiat risk of immediately converting NLG to fiat for the merchant reimbursement, they have to sell NLG at market price to offset any fluctuations in conversion rate. 3rd party processors are a band-aid fix for the real problem of NLG not being a working and usable currency.
Extended block times is crippling the adoption of NLG, it prevents wallet to wallet transfers for payments, which is absolutely essential for increased adoption of NLG. Dependence on a 3rd party processor for quick transactions limits the use of NLG to those merchants that use the 3rd party processor, which stifles circulation from wallet to wallet between users that would hold NLG for future payment of goods or services, instead transactions are funneled through payment processors that are putting the NLG on the market to fulfill fiat obligations.
I am not concerned about the price or the difficulty, my concern lies with the lack of usability.
There is not need to panic, this is not the end of NLG, but must be addressed effectively and urgently.
As I posted before, I believe that adopting the BTM diff algo is a very effective solution -
