For a sane person, he would fake multiple Bitcoin accounts to get more and then collect them and exchange them for cash. Others will trade practice. For me, I probably won't care much about it because its value is too low or gambling at the sites.

This thread caught my attention unintentionally.. I still remember the time when I first registered as a member to this forum (that was back in 2012). Back then, there were a lot of give-away threads, where experienced users would simply donate BTC0.01 or BTC0.005 to the new members. Back then BTC0.01 was worth around $0.05. But the same coins will be worth $360 now. So you can compare what would have happened, if you used those coins in each of the six options listed by the OP.

Some of the users might get irritated at me for posting these old stories again and again.. but I can't help. Bitcoin completely changed my life. I am still nostalgic about the time when I first joined this forum and made my first posts.

This one is the most possible thing to do with £10 Bitcoin. It is not a proper number of BTC to hold in a wallet and you hope to earn profits then. It is a too small number, just assume that it is just the beginning of a serious BTC investment. Of course, need to buy more to expect profits from holding BTC on a wallet. At least, we should hold around $100 in Bitcoin to expect profits.

For me if you are going to ask me, I have a simple answer to that. And that is to buy another crypto using the money. It was given to me free anyway, then I can gamble it for some startup coin. Of course the question is, is it easy to buy that coin I fancy or not. If its ethereum based then forget about it. I need to buy ETH from a shop then possibly transfer the ETH to the wallet where you can invest it to the shit token you wanted but that would cost a big fee. So I think I will invest it on something I can buy on Binance.

I'll just keep it for what it is and just wait and see whether it'll appreciate in value over time. £10 is an extremely low amount in crypto but given the increases that a cycle has, I will not be surprised if it doubles itself just within a decade. After all, I do have my own stash that I'm using for buying and selling, so setting aside the free £10 wouldn't hurt really.

It would be done as an experiment, though. In today's rates, the transfer fees would be insanely high that it wouldn't make sense to use the said amount to gamble, or even if the transfer rates were to be set at 0, it would still take days for the amount to be transferred before I can play, and I have no time for that. Compared to my initial decision, I wouldn't have to do anything at all and that 10 quid would be useful to me.

A little bit clarification as posters on this thread does have different responses because some do believe that it is 10M in worth or just simply  £10.
I doesnt many any sense if we do talk about  £10 because this is just as small amount and nothing you can do much about it.
So i presume this do talk about millions or OP had just edited it out since some people had mentioned about million.

It is free so I will hold it and see how it goes from there. Learn more about BTC and hoping to invest more on it. It is a small amount of money and it will only be eaten by the fees if you intend to cash it out. It is a good initial investment since it is free.

I had my first BTC from faucets which would have cost a lot now if I was able to keep them when I first started.

I think I would do, what most newbies will do... which is nothing.

Let me explain... Most people fear the unknown, so when faced with something unknown.. they will do nothing, until they researched the new thing that was presented to them. When they fully comprehend what the "new" thing is, it will either tickle their curiosity and they will investigate further OR they will not be interested and simply find a way to get their hands on the "cash".

I have seen this first hand, when I gave people a "Paper wallet" with some bitcoins for Xmas... I would say more than 80% of those coins are still on the paper wallet and only 20% of those coins have shifted to a new Bitcoin address. (possibly transferred to an exchange to be converted to fiat currencies) 

If I were to have the mind I had 8 years ago, I would've most likely spent it. Worst case, I would've lost it somehow.

Considering my today's mind, I'd hodl the hell out of it and continue to accumulate more! Those £10 will be valuable over the long term. It's all about a matter of time before today's £10 worth of BTC will become a Romanian minimum monthly wage, lol.
