Some of us were rather slow to get on the bitcoin train and to a certain extend missed out and we are trying to play catch up. We did not have the vision that the price of bitcoin would be where it is today. In fact some even thought that  it was very awkward concept.  Now the mining costs have also increased.  So my humble advice to people is this. Just accumulate all the free cryptocurrencies  that are available today.  You never know what will happen tomorrow.
