(Bloomberg) -- Bitcoin seems to be stuck in a rut. 

Investor interest in the largest cryptocurrency and its offshoots is waning: prices are flagging, online searches for Bitcoin and other digital assets have fallen off, fewer and fewer coins are changing hands, and crypto-related funds are seeing massive outflows. 

In fact, a UBS analysis of around 160 products shows April is set to see the largest crypto-ETF outflows on record, with investors having pulled more than $417 million so far this month. A Bitcoin product from Purpose alone has seen more than $220 million come out since the end of March. 

In other words, the novelty of crypto seems to be wearing off again, like it did after the boom and bust of 2017 and 2018. The space is also no longer notching the huge influx of new investors that it had seen in the past two years. 

“The vast majority of the population seem to have little interest in crypto because it’s too complicated, too volatile, too strange,” James Malcolm, head of foreign exchange and crypto research at UBS, said by phone. “So in a sense, we’re stuck at the moment.” 

Cryptocurrencies, just like other assets considered to be riskier or more volatile, have sold off this year as central banks around the world raise interest rates to fight persistently hot inflation. Bitcoin reached a peak of near-$69,000 in November before commencing a selloff and hasn’t been able to recover since. It’s down roughly 40% since that record. 

Aggregated trading volumes across crypto exchanges like Coinbase and Kraken have also fallen off as interest remains muted and the flow of new investors dries up. Meanwhile, Google searches for the word “Bitcoin” have also declined, and social-media activity via the Crypto Subreddit -- as measured by things like comments and posts per day -- are down from mid-2021 levels.

So what needs to happen for interest to perk up again? UBS’s Malcolm says industry participants want greater regulatory clarity, something that might still be a long way off. If prices started to rally again, investors could return once again.

“It either needs new people or it needs existing players to dedicate an increasingly large slice of resources to the industry,” he said.

One reason Bitcoin’s been stuck in a rut is that a lot of the coin’s supply has been moving into long-term-holder accounts. Analysts at Blockforce Capital, who used Glassnode data, cite the “massive amount” of the coin that’s been coming off exchanges recently -- that gets taken “offline” and put into cold storage, meaning it’s not likely to be traded. The number of illiquid coins is not just growing, but the rate at which it’s doing so is accelerating too. 

But the data could be hiding a silver lining. “We have only seen this level of outflow from exchanges four previous times since the start of 2018,” the analysts wrote in a note. “Three of those instances correlated with a sharp upward movement in price not too long after.”
