Coach Dav Whatmore insisted Bangladesh cricket is a "sleeping giant" after their shock win over Australia.
"It is nice to have more positive vibes and show everyone we can compete if we do a few things better," he said.
"When you hear people saying 'Get rid of Bangladesh', it is disturbing and it hurts. The potential is there.
"There are individuals starting to come through. It really is a sleeping giant. We just need to wake it up and nurture it a little bit."
Bangladesh's victory in Cardiff sparked secenes of celebration back home with thousands taking to the streets.
"I just think that we have done something that we were all hoping that we could do," Whatmore told BBC Sport.
"Certainly I've got to pinch myself. It's fair to say that everyone would expect the number one ranked team to account for Bangladesh.
"But that is the beauty of one-day cricket I guess.
"We have every inch of respect for the Australian team, but again in a one-day match where you start and finish in 100 overs, there's a result - and as we've seen here, it can happen.
Whatmore also said the victory was a tremendous boost for his side following their tough time against England in their recent Test series and opening NatWest Series match.

"We are very pleased to bounce back from a series of pretty demoralising defeats in the recent Test matches and the first one-dayer," he said.
However, he questioned Australia's decision to bat first after winning the toss.
"I was a little surprised - you look at the wicket and you make a judgement. It looked OK but I thought that there was a little bit of moisture and it was worth having a bowl first," he said.
"I was a little bit upset at our batting total. I thought a good side would have restricted Australia to a score perhaps 20-25 runs less than that.
"But given the lack of experience of our bowlers, I settled for Australia's 249-5 - and there was no real sense of panic in our reply."
Whatmore also challenged Mohammad Ashraful - who became only the second Bangladesh batsman to hit an international ton - to reproduce the form he showed in this match in future.
"We have always known what the boy is capable of, he just doesn't produce often enough - that's the frustration of it," the coach said.
"This is the sort of innings that we would like him to play more.
"In his first Test match innings against Sri Lanka he got a century and the hundred he got against India at Chittagong last year was as good as any I have seen.
"But he's here and there. In between there are a lot of innings where he under-sells himself and under-performs.
"I'm just hoping against all hope that he understands now a little bit about what you need to do to be more consistent."
