If you are aiming for higher valuations and potential possibilities better not to focus with inly two coins but instead explore and split your money, tops 10 coins for long term investment would be fine as you will need to buy and hold then wait till the value you wanted will be achieved, sell out and repeat the cycle, but its always be depend from how you look for your investment and how long you are willing to play with your chosen projects.
it will require long-term market analysis. it won't suit him. select coins with movements at certain moments. like BNB that move quickly when their launchpad events begin. it will benefit even at close range. no need to wait too long.
