I don't see a big difference even if we use a big capital. I even think it is better to choose other altcoins when Dogecoin isn't very profitable anymore. SOL or XRP looks better for the option of altcoins investment. There are many people who leave Dogecoin, they prefer to choose SOL, XRP, TRX, TON, or another potential altcoins. Recently, SOL and XRP are the altcoins which have big daily/weekly price moves.
Uhm, I think capital influences our investment decisions.
If I had a large capital, I would be afraid of losing my capital and I would invest in BTC and top coins like ETH, SOL, XRP, BNB, ADA... Conversely, I would tend to take risks to get more profits and I might gamble with the market by buying dozens of memecoins in hopes of getting rich overnight.
The interesting thing is that DOGE is both a top coin in terms of market cap and also a memecoin. It has become an investment target for many people, but its large market cap has hindered its growth. I still believe that at the right time DOGE will have a new ATH of its own this season.
