Yes you can make a lot of money with the bitcoin and the fact is also that long terms are very good for yourself too.
Its very nice to do and its profitable too and you have to do nothing.
If you do possess huge amounts of bitcoin then holding would be good idea too because you would surely made profits on future but if you are just holding small amounts then its better to invest those up in able to grow rather just holding it. Seeing profits on short terms are the best too.
