brother , investment is with your own risk. anyone can suggest you something without any reason. it is better to invest in what you understood well from the list you provided here .i know all of these are good projects which has protentiol to perform well in future. but do it with your own research. find about project team , fund rising , tokenimics and others well . good luck.
The OP is just asking people on this forum for advice, there is nothing wrong there, everyone knows that Investment is a risky thing and the only one who bears the risk is the Investor. My advice to you, if you know a little bit about the projects the OP is asking about, you can give your feedback from as far as you know about those projects instead of just arguing about general explanations about Investments, LOL.
Between Skale Network, Satoshi Island or Lido Dao which one do you think will be better investment in this bear market.
It all depends on your goals, whether you want safe Investments with lower volatility or Investments with higher volatility and have a very high ROI if the price goes up. For a safer investment and low volatility, I advise you to buy
$LDO, this project is at number 69 on CMC and the highest among the other 2. for a riskier Investment with a very large potential return (high ROI), you can buy
$STC, the volume in this project is very low ATM. But from the safest and most risky, I prefer Scale Network, this project has a fairly high ranking in CMC and also the MC is not too big, it looks like the price of
$SKL will be easier to rise if the market trend starts to recover later.
