So I bought some Ethereum for £1070 a few days ago and it is now worth £1326. Would now be a good time to sell for a small profit?
almost 300 euro profit is not a small gain , So forget asking about your small profit here .
I am investing more long term in Bitcoin but wanted to trade a bit on smaller coins i.e Ethereum etc.
You had answered your queries , it is clearly that you are a Bitcoin long term investors but wanna do some trading outside of Bitcoin is what you have now is a perfect chance for you to have income.
then buy another altcoin that has potential in increasing sooner.
