It depends on how the business works. Some businesses die forever and do not have any development.
Sometimes we will be lucky to choose a good alts. but if not lucky, we can lose everything because the volume is low or there is no need to buy.
Therefore, this is also a chance strategy. You should consider and analyze carefully before buying.
