Very bad tokens for sure. This kind of projects were putting very big task as the main source to get income rather than pegged on the performance of its product. If the product working so well and i do believe if this will also give a very good impact to the price. This will not sustain for long term. people will not always paying the big tax only for a single transaction. Im seeing so many projects used this kind of strategy have become failed project.
it may looks so attractive for long term but in fact if this kind of project can't sustain for long term. You must always be careful with it. This is not good as an investment
