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.
28 btc is a good amount to have and its good to diversify them to different wallets to minimize the risks of loosing them as of now I am having less then 5 bitcoins in my wallet but I am trying hard to increase the level of bitcoins in my wallet as I am sure that price will rise in future so having more volume of coins can give me higher returns in future.
You can increase your less than 5 bitcoins by doing any kind of investment like joining an ICO or investing in different legit sites and also doing trading which have a less risk of getting lost since you will manage your own money and you are in charge of how you will take profit from it but don't forget to study the basics first before risking your less than 5 bitcoins.
