The market overall is not doing good due to Btc price. If we change the Block reward now to 50 Pawn, the miners might abandon Pawncoin because of low profitability. There's no guarantee that those that got Pawncoin at 500 per block will not continue to dump at the price.
Why do we need miners? Lets switch to POS, its more secure. Use Proof of burn to transfer all PWN currently existed. They will continue to dump even if the price is going up, miners especially the multipool will be the buy wall.
Even if the value stays as it is, as long as the volume and price is stable, people will use it for your PAWNShop when your pawnshop becomes profitable you can pump the price. That is the long-term strategy.
