I believe that having a huge wide net in the crypto world right now is not a smart idea. I get that it could be a wonderful idea when the bull comes, but that's usually with the new stuff and not very old stuff all that much, they do not go up as much as you think, not enough to make you rich at least.
You should hold, btc, eth, bnb right now and wait for them to do like nearly 10x or so, at least 5x anyway, and then you would put most of that profit into brand new stuff, like literally before release, ICO level stuff, and then you will use that profits to withdraw and just keep the bitcoin ones. Turn your 10k of bitcoin to 100k, then take out 50k of it, spend the other 50k on silly new stuff, and then withdraw profits, and keep that 50k of bitcoin there. That's it.
I have a bad experience when holding new projects in the long term, because based on my experience most new projects are only used
for pump and dump. So the risk of experiencing a loss is quite large. So like you said, we should just focus on holding old projects
like BTC, ETH and BNB. Although the profit generated may not be as big as new projects, but at least the risk is not as big as investing
in new projects. In fact, I would say that investing in popular old projects is relatively safe, because so far, popular old projects recover
faster when the price drops. So even if we invest with large capital, we don't need to worry, as long as we can be patient with holding
until the price goes up, we will definitely get profit. My advice is not to be obsessed with big profits, but make sure we spend our money
investing in the right and safe coins.
