Diversification is the key and one should have investment and should look at the opportunity where exists and in future which sector or segment will boom and invest accordingly. One should always stay in crypto and you can choose the coins which you can bet will grow and give you better returns.
This is effective in crypto as well, that is why most of the traders diversify their investment to make sure that they can earn profit and win with more options. But this doesn't mean that they should stop observing their investment.
Going back, what I perceive about earning and saving in satoshi is that we don't need to buy a whole 1 bitcoin, because too soon, people will value sats as we value 1BTC as of now.
