Given the expected bullrun, in my opinion, you can simply buy Altcoins from the CoinMarketCap Top 10 and hold them until the price soars. In any case, these coins will show good growth because of the huge demand for them.
if the market increases, all assets will certainly follow the increase. but I think a coin with a top 10 position does not guarantee to follow with good conditions. where some assets that we don't expect usually have better growth.
