I discourage you that not to invest into sports betting it is not called as investment either but it is gambling and we all know that most of the people who are playing with gambling are not being successful. And possibly that 10 bitcoin will be lose in gambling if you are not going to be able to invest that into something profitable.

I think that the best option for me at the moment is to save them because I think it is better to wait for the price to rise again before trading them.
If the price is at a price that I like then I might trade them in.

You are into long term investment and that is good, the price will certainly rise as we have seen now it slowly rising although not that substantial but wit proper patience we will do it with the right timing and we can sell our bitcoins with a bigger profit.

Holding  bitcoin would be good for  long terms but  its ideal  thing to do  if you make  investments with it so that you would  enjoy profits on  short terms.  10 btc is  enough already to make  such investments as  you said  trading  would be  good but  you would  need  knowledge  to be profitable on  trading.

Yeah and I think trade and investment will give better profits in compare to holding, and it trading will also grow your coins in future which is never possible with holding.

Holding can probably give someone profits in long term but that profit wont be as much as much someone can earn by investments and as the guy said 10 bitcoins is not a small amount, if we use that in trading we can earn some good profits in short term instead of waiting that much.

By holding 10 bitcoins for long term, they will always remain 10 bitcoins.
So we should invest them or loan them to someone trustworthy so as to make the bitcoin stash growing.

By hanging on to 10 bitcoins you eventually end up with 10 bitcoins. By 'investing' or, god forbid, loaning them you can subtract 10 from that figure in a wonderfully small amount of time.
