I want to change 0.25 dollar cents in bitcoin for my digital content, is it too little?
currently that's not feasible with bitcoin due to its price. The alternative is to use another coin with a lower price to make it truly a "micro-transaction" with sub-penny fees. But the problem with scenario is your users will now have to buy that coin just to buy your product. Check coinmarketcap.com for a list of coins to use.
