which one is more reliable to increase prices
none of them.
price only rises under two circumstances: 1. with pumps 2. with adoption.
the pumps are obviously what has been happening to altcoins and tokens but they are not sustainable, eventually the dump comes and prices go back down to initial value and lower than that.
the only way to increase the price is by adoption and for that the coin has to have use cases in the real world otherwise it doesn't matter how much tokens you burn or do whatever else, the coin is doomed to die.
