Actually it depends upon the miner that for which thing he is making mining , if he will mine bitcoin like big coins then surely it will not be profitable for him ( from the normal conditions that we have in our life ) and also it is big amount of money consumption thing in starting .
But here if we will go for the token buy directly then that will be in discount , so in my opinion better to go with the buy of the tokens and Also here we need to take care whether we are going to buy entree tokens or just worst ICOs TOKEN otherwise we will lost everything in such types of the Strom of the cryptocurrency world .
