So if you're asking yourself can I invest? Is bitcoin worth investing in? Is it smart choice to invest? Then you need to understand the challenges involved, the pros and cons, what makes it difficult to invest or not.
I know i am replying late but your main concerns seem to be about the ordinals problem which had congested the network with so many transactions that the BTC blockchain is taking days to clear that congestion and in the period more transactions keep coming and increasing the congestion. Well, you are totally right about one thing that BTC has some scalable issue that needs upgradation one is processing/validation of transactions at a faster level so that mass adoption of it could occur. For example, i have talked about it a
few times before but let's talk again If El-Salvador uses BTC and makes many transactions in a day like if 90% of their total population makes transactions on the BTC blockchain then it will take 10 to 12 days to process those transactions which means if we currently watching congestion on BTC mempool explorer 12 days and it will become 22 days then.
I had talked about it earlier too, when the ordinals are not released yet but many there was news going around on many news websites that developers are working on deploying tokens onto the BTC blockchain. (

Now coming back to your query about investing in BTC then it is a totally different thing from an ordinal issue because for some people it is a problem or loophole or issue from which other people no wonder are earning a lot but they hate it and then there is another group of people who supports ordinals it includes many devs too. The point is, BTC is here to stay long and ordinals is just an upgradation that will bring more improvements in BTC no matter how it is impacting it now because, for those it is an error, they will try to come up with solid solutions that will make it better then before.
