I can't recommended which one better between Skale Network, Satoshi Island or Lido Dao for your investment in this bear market because I am not really popular with your altcoin list option. Better investing your assets with potential and top standing position on coinmarket cap like BNB or Ethereum. If you think between Skale Network, Satoshi Island or Lido Dao have potential for the future better make your research and checking which one of third coins have potential for the future. Not really worth when asking other opinion because some of them know how risk when investing in some coin without have good potential and still not popular around investor or trader.
The three projects mentioned by the OP are not popular, so the OP really has to do research and analysis well to get to know the three projects.
Because the results of research and analysis done alone are better than asking other people's opinions, however we must be familiar with
the choice of projects that we will choose. Don't invest in projects that we ourselves have doubts about, it will only waste our money.
Based on the analysis I did among the three projects mentioned by the OP, I think it's Scale Network that I can quite recommend, but the risk is
quite high. If we really want a safer investment and lower risk, as you said investing in top coins is much better. But as long as we have done research
and analysis of the projects we are going to buy and we dare to face the risks, why not try investing in these projects. So the decision is in our own hands,
so make wise and calculated decisions. Do not make decisions because we are influenced by what other people say.
