Between Skale Network, Satoshi Island or Lido Dao which one do you think will be better investment in this bear market.
I doubt that many members have ever heard of those coins so it is not really possible for us to give you meaningful advice when we do not really know anything about those coins, you probably know way better than us which coin may be slightly better than the other, however the fact that you are coming to the forum and are asking those kind of questions tells me that you're not confident in your skills as an investor in order to make the decision on your own, that should tell you all what you need to know about whether you should invest in those coins, I recommend that for the time being you do not take any kind of big decision when it comes to your money because most likely you're going to make a mistake if you do.
Maybe he is a newbie and he does not have much knowledge to choose for himself a project that is really worth investing in and he needs everyone's help but unfortunately, all 3 of your projects mentioned are very little known projects so no one can give you the best advice. There isn't even any link to those 3 projects and I don't think anyone will sit back and look up what these 3 coins are for him.
My advice to OP is: as a beginner to the market you should invest in top projects and bitcoin should be a priority in your portfolio, you should develop your skills before you want to go further in the crypto market. Hasty investment will not bring good results
