Lol if you’re really expecting all these coins to be used for purposes as you have defined, then you’re getting it wrong because that’s never going to happen, people are not interested in using most of these altcoins for transactions , the choice for use is mainly bitcoin and anything else apart from that is hardly considered as a choice by many.
There is always purpose for every coin or token, and BNB is not a bad example, it’s a good coin and is serving the purpose for which it’s meant for. Some companies may decide to create a coin and limit the usage to their platform alone, I don’t see anything wrong with that, and it doesn’t that coin is not going to be successful, as long as the team knows what they are doing the coin will be a success.
Of course, personal tokens of each of the cryptocurrency exchanges suggest the presence of certain bonuses and benefits for each user for trading. But I practically do not see a single cryptocurrency exchange that would show good results for its tokens. An exception is the combination, because BNB really showed good progress, but nevertheless, such a rise in the price of BNB is primarily due to attracting new investors through new IEO projects on the Binance. If these projects do not show good results in the future, BNB will be able to worsen its position in the cryptocurrency market.
