You are right, given the state of the market Bearish buying the top coins to invest in is a good idea without doing the research as you said, from the state of the market I also see that by buying top coins without doing any consideration, strong analysis and without doing research it seems this will be a regret, so his advice if you want to make an investment you need to underline that doing consideration and research is very important.
The top coins are coins that are already very well known in the market so everyone only does a little research because top coins like Bitcoin are coins that can still recover in the market even though they are currently experiencing a decline in price, but owning Bitcoin and holding it until the market is bullish is which is a very good thing, because everyone just needs the patience to wait for it.
Need patience and good sense of timing, you can buy every deep and hold your asset till the strong bull come out inside the market.
We can hold still those asset that have good fundamentals and have strong community support, the big factor that community will
stick to a project are the usages and the progress that the team continue to bring. With that, you can lean and continue to hold the
coin even it will take longer but once the market bounce back, you'll earn a lot.
