You can start with at least four digital assets you mentioned maybe except for DOGE as it is a memecoin and old memecoins are getting out of flavor in the current market - they are losing excitement new ones are generating especially if endorsed even subtlety by CZ. Now, I actually don't believe that crypto adoption is spreading too fast...it is actually the other way around especially from the POV of people who had been here in the industry for years. I am glad that things are heating up in Nigeria, a country considered in the top 5 in terms of adoption and can be the oasis in the African continent.
You should also understand that many new meme coins has been ravaged with pumps and dumps scheme, unfortunately i still think that the old meme coins are more safer for near future investments.
I have not seen any new meme coins that has consistently maintained a good marketcap, trading volume and large community than Dogecoin, Pepe, Shibainu among others.
In short, most new meme projects are very risky, check the Trump, and Melenia meme coins that were launched recently, both has dumped beyond the expectations of many crypto investors/traders.
In my opinion, it is not advicable to invest on most the new meme coins that are not measureble to the old meme coins in terms of marketcap, trading volumes, and Coinmarketcap ranking.
