I agree with you that negative thoughts will never make our lives positive. so, in any case we have to look at the positive side
We should look from a positive angle, and be committed to it because positive thoughts only does not give us positive results. We just need to be engaged to it and feel it as if it really happened. Therefore, it will happen. Aside from the positive thinking, patience is required because without patience, the results will not pay off. Positive thinking plus patience plus committment equals good results. Trust me, nothing comes with easy work.
Yes we should have an positive thoughts in crypto currency even in blockchain technology, but in reality it is very difficult to think positive while the market are dropping and we can't deny it.
