2. Would you leave it and watch it hopefully rise.
3. Would you sell it.
4. Would you trade it for another Cryptocurrency.
5. Would you buy more Bitcoin.
6. Would you do something else with it.
Say what? The feed on sending BTC is $15 right now, so your 10 quid isn't even enough to cover fee's to spend it, say you had $20 USD, then could send a friend $5
If you sold you would lose on the transfer, and the exchange 20% grab, you would still get zero
Say I buy $100 USD of bitcoin, I get $80 because of exchange losses and fee's, then I transfer to my address and I lose $20, then I go to sell it and I take home $50, this is bitcoin.
10-GBP is like 0.000001 BTC these days, smaller than the transaction fee, you have entered the world of nothingness
Next time say 100-EURO, then you can watch it become 50-EURO in just a few transactions.
