While it makes sense to think long term and begin your search for a coin which will do well after the bear market is over, at the same time I think it is a mistake.

We need to concentrate on what it is happening now, and right now the market is not on the best conditions and it could even begin to go down again, so you need to take some decisions to protect your capital, and investing in bitcoin seems like the best choice, after all not only the price is low, we also know that when a bull market first appears it is because bitcoin leads the market leaving altcoins way behind, only once this process has lasted for some time altcoins wake up and imitate the movements of bitcoin, then and only then you could begin to worry about which altcoin will be the one which can give you the biggest profits.
