I would like to share with you a little bit of experience. When the bull market comes, don't do contracts or speculate on coins. If you have a lot of money, it's okay to choose some mainstream coins for spot quantification. In particular, don't spend too much time and experience on local dogs, because the project parties who issue local dogs are considering cutting more leeks and making more oil, and then hoarding mainstream coins. Therefore, choosing valuable and potential mainstream coins for layout is the kingly way. You can consider the following aspects when choosing mainstream coins: technology, track, capital, exchange, multiples. If there is a reliable community that agrees on mainstream coins, you can also participate appropriately. Hoarding coins + making money is the big winner. After all, how many chips do you have in your hands after the bull market starts?
