I saved only 2 bitcoin but i am happy because i got profit in that. Now I would like to earn more bitcoin for my future because i know one day bitcoin become usefull to everyone.
I have about 28 BTC in total but spread in several wallets for security reasons. I think it's good to have some saved for emergencies and for future profits as soon as the price rises.
This is a good amount of Bitcoins, and I believe the results you will get will be satisfactory as long as you are willing to hold the coins for the long haul. I think it's possible to have bigger gains if you invest in trading, but if you do not have experience, I think it's best to be patient and save your coins.
