I don't think Satoshi will dump all of the one million coins at once. If he did, people will be rejoicing since it will pump bitcoin down so hard that late comers will be able to buy at a really low price. I see no reason as to why would he do that though. His mission was to create financial freedom for the masses and he did great with that. I do think that Satoshi will instead dump his bitcoins little by little (e.g. 1BTC a day sell) and then just carry on with his life living as a bitcoin millionaire. Satoshi probably have more than 1 million bitcoins since he is one of the first ones to be here, might as well be the first one to mine bitcoin and there was no bitcoin halving yet at that point so the mining rewards are a lot more than as of today.



So basically it's a case to case basis. If you have no idea about day trading, you'd be better off without it since doing it will just open a huge chance of you losing your bitcoin. It will be a lot better if you just hold your bitcoins instead.
