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.
This is the first time I heard of those, but if OP is a risk taker, then just divide your investment fund to three at least you made some diversification and won't regret of missing one of them. But honestly, just spend a money you can afford to lose in a project that has yet known future.
