Your intention at that was for long term investment because you believe that bitcoin have a value. Then you can compare right now, how much profit that you've got? You will be a millionare now whilst you just spent $100.
I really believe that bitcoin is potential's investment place, its features is really suitable for human being right now and even I predicted that bitcoin can't be separated with human being in the future. The people will use it and choose it like the basic stuff.
That was only a dream because that is already happening in a long time ago. No need to dream, but we have more opportunity to make money from bitcoin now and in the future. But I am sure if people can see what is going on in the future, they will buy as much bitcoin as they can and hold until this time. They will make a lot of money, and they will become one of the wealthiest people in the world.
But if we try from now on, and we can collect from satoshi, I am sure that if bitcoin price increase so high, in this case, bitcoin price will increase more than $100k in 2025, then we will make a lot of money than now.
