Perhaps the biggest crypto news of the last week of March is that South Korean cryptocurrency exchange Bithumb reported a recent hack and theft of EOS (EOS) worth about $13 million. Bithumb disclosed that attackers stole 3.07 million EOS through one of the exchange's Internet-connected hot wallets. The top exchange said on Saturday that it monitored an unusual EOS withdrawal and has suspended withdrawals and deposits afterward. Bithumb said it suspects the theft was committed by an insider and is currently undergoing an internal investigation. Korean law enforcement has already been notified. It's the second hack of Bithumb in two years.

Here is the rest of the week in review:

The US Securities and Exchange Commission (SEC) once again postponed its decisions on a rule change allowing Bitcoin (BTC) exchange-traded fund (ETF) applications. The SEC delayed a final decision on ETF applications from Bitwise Asset Management and NYSE ARCA, as well as from VanEck, SolidX, and Cboe Global Markets (CBOE  ). The SEC said its new deadline on the decisions will be May 16. The SEC has already received 21 comments on the proposed rule change. The new delay marks a year since the first BTC ETF proposal, but many remain optimistic. Recently SEC Commissioner Robert Jackson said he believes a BTC ETF proposal will satisfy the SEC's standards eventually.

Tron (TRX) founder and chief executive Justin Sun stirred up controversy in the wake of a Twitter (TWTR  ) giveaway contest. Sun had promised to give a lucky winner who retweeted a tweet a free Tesla (TSLA  ) vehicle. Then after a winner was named, he said there was a glitch in the selection process and would redo the drawing on live video. But he said the prize would change to a free ticket to the next Tron conference. After Internet backlash, Sun announced he will give two Teslas to two winners and added he will give away $20 million cash in airdrops soon. A Tron spokesperson said the incident does not have any bearing on the project, as the giveaway was a personal one from Sun.

Crypto prices rose convincingly this week to above $144 billion. EOS, Cardano (ADA), and Ethereum (ETH) led the gains in the majors. Tron and Bitcoin SV (BSV) slipped slightly. In the top 100, the biggest losers are ABBC Coin (ABBC), down 27%, Unobtanium (UNO), down 18%, and DigiByte (DGB), down 14%. The biggest gainers are ZClassic (ZCL), up a whopping 97%, Tezos (XTZ), up 56%, and Elastos (ELA), up 43%. In the next week, traders will likely watch how well Bitcoin can stay above $4,100 and whether cryptocurrency can breach the $150 billion resistance level.
