Bangladesh coach Dav Whatmore described the side's capitulation to West Indies as "painful for everyone connected to Bangladesh cricket".
The 138-run defeat follows an emphatic nine-wicket loss to South Africa, when they were bowled out for 93.
"The end result was what we expected by the way we reached it was disappointing," said Whatmore.
"If we bat first we lose wickets and if we bowl first we can't take them so we get hit at both ends."
Bangladesh allowed West Indies to rack up 269-3 after putting them in to bat.
Wavell Hinds was dropped twice and Chris Gayle one in a record-equalling opening stand of 192.
"It helps if you take catches," Whatmore said bluntly.
"We didn't use the new ball as well as we would have liked.
"We were unlucky not to take wickets early. The young boy Nazmul Hossain bowled well - he was the only one."
In fact, Whatmore believes the showing of Nazmul, along with former Under-19 team-mates Nafis Iqbal and Aftab Ahmed - both batsmen - was one of the only positives of the tournament.
"Each of the batsmen showed enough and the bowler was the best in both games," he added.
"That is far more of an indication of what we might expect.
"There are a couple more players who are promising and might come through later this year and to me there's a future there."
Whatmore tipped South Africa as the team to progress from Group B, as they face West Indies at The Oval on Saturday.
