Just buy some BTC and hold it.
Thanks for the advice , however this method relies solely on speculation , and I see more potential in the mining sector , as at the current rate of 25 BTC for every 10 mins , it will take another 3.8 years untill all the possible bitcoins are mined .
By the way , will the processing fees will be enough to sustain the existence of the bitcoin miners once all the bitcoins are mined and there is nothing else to mine . Assuming the Bitcoin doesn't fail in the meantime , will the processing fees cover the expenses of miners or would they be able to make any kind of profit ?
