Nov 13 (Reuters) - Bitcoin broke through the $90,000

level on Wednesday, to an all-time high in a rally showing no

signs of easing on expectations that Donald Trump as U.S.

president will be a boon for cryptocurrencies.

The world's biggest cryptocurrency has become one of

the most eye-catching movers in the week since the election and

on Wednesday touched a record of $93,480 before paring gains.

It was last down slightly at $88,185, but has risen 32%

since the Nov. 5 election.

Smaller peer ether has also risen 37% since Election

Day, while dogecoin, an alternative, volatile token

promoted by billionaire Trump-ally Elon Musk was up more than

150%.

"What you've seen since the election is the market hoping or

realizing what that could mean for bitcoin in the medium to long

term - a pro-bitcoin administration, Senate and potential

legislation that not only gives U.S. citizens the right to

self-custody bitcoin but potentially for bitcoin to be a

strategic reserve asset for the U.S. Treasury," said Damon

Polistina, head of research at Eaglebrook.

Regulatory uncertainty has been a major cloud hanging

over the sector and a headwind to advisors allocating for their

clients to bitcoin, he said.

Trump embraced digital assets during his campaign, promising

to make the United States the "crypto capital of the planet" and

to accumulate a national stockpile of bitcoin.

It is unclear how or when that could happen but the

possibility drove a speculative surge in crypto mining and

trading stocks.

Zach Pandl, head of research at Grayscale Investments, said

the "election results will open up the ability for large,

regulated businesses like banks, custodians and exchanges to

engage with public blockchain technology in the way that they

haven't in the past."

Software company and bitcoin investor MicroStrategy ( MSTR )

announced it had spent about $2 billion buying bitcoin between

Oct. 31 and Nov. 10. Shares scaled a record high on Tuesday.

Crypto investors see an end to increased scrutiny from the

Securities and Exchange Commission under Trump. Trump and his

sons announced a new crypto business, World Liberty Financial,

in September.

"Many people believe that we will inevitably get to bitcoin

at $100k," said JJ Kinahan, CEO of IG North America and

president of its tastytrade retail brokerage.

"I expect bitcoin to continue building momentum, at

least until after the inauguration when we find out what the

real plans to get there are."

Others advised investors against getting caught up in

the crypto frenzy.

"With bitcoin reaching $90K and hitting a new all-time

high, investors should be cautious about the potential

volatility ahead," said Georgi Koreli, CEO of Hinkal, a

blockchain-based private transaction protocol. "This doesn't

mean that we will not see $95K or even $100K soon, but rather

that BTC might pause or slide back to regain its strength."
