Cathie Wood is planning to launch a new Bitcoin exchange-traded fund (CRYPTO: BTC) (ETF). That's not surprising, given that the creator of ARK Invest has long been a supporter of cryptocurrency.

The Securities and Exchange Commission (SEC) in the United States has yet to approve Wood's Bitcoin ETF. You can bet that if and when the regulator authorizes the ETF, many investors will hop on board.

Wood's other ETFs hold stakes in several stocks that could outperform cryptocurrency-focused stocks in the long run. These three equities are better investments than Wood's Bitcoin ETF.

Sea Limited

Over the last month or so, two of Wood's ETFs have sold some shares of Sea Limited (NYSE: SE). On the other hand, Sea is the fourth-largest stake in the ARK Fintech Innovation ETF and the 17th-largest holding in the ARK Next Generation Internet ETF.

Since its IPO in 2017, the shares of Sea Limited has increased by almost 1,500%. This is more than three times the return on Bitcoin over the same period. Sea, I believe, will also outperform cryptocurrencies in the future.

Garena, the company's esports and mobile gaming division, has the highest-grossing mobile game in India, Latin America, and Southeast Asia with Free Fire. In Southeast Asia, Indonesia, and Taiwan, Shopee is a leading e-commerce site. The company's fast-growing mobile wallet is called SeaMoney.

Gaming, e-commerce, and digital payments are three of the fastest-growing areas globally, and Sea Limited is focusing on them. It also focuses on fast-growing geographic regions, such as Southeast Asia and Latin America. Sea is expected to continue winning.

Without a doubt, Wood's favorite fintech stock is Square Square (NYSE: SQ). It's the ARK Fintech Innovation ETF's top holding. The ARK Next Generation Internet ETF ranks it fifth. It's also the ARK Innovation ETF's sixth-largest holding.

If the SEC approves the Bitcoin ETF, don't be shocked if Square is included among Wood's holdings. On the Square Cash App, you can purchase and trade Bitcoin. The firm is also a strong backer of cryptocurrencies. "We see Bitcoin as the internet's potential to have a native currency," Square CEO Jack Dorsey said during the company's first-quarter conference call.

However, Bitcoin is only one component of Square's overall plan. The corporation has two ecosystems, one for enterprises and one for individuals. Square has previously made more money from its business (or seller) ecosystem. Still, it has significant growth potential on both fronts, including the possibility of combining the two ecosystems in some ways.

Square's stock is trading at close to 167 times projected earnings, which is a nosebleed value. However, I agree with my Motley Fool colleague Travis Hoium that the company has a lot of room to rise, particularly with the development of its financial services.

Teladoc Health

The ARK Genomic Revolution ETF's top holding is Teladoc Health (NYSE: TDOC). In the ARK Innovation ETF, it is ranked third. The ARK Next Generation Internet ETF ranks it fourth. Wood's ARK Fintech Innovation ETF holds Teladoc shares.

Over the next five years, can Teladoc outperform Wood's planned Bitcoin ETF? Yes, I believe so. According to McKinsey & Company, there is a $250 billion annual opportunity in virtual care in the United States alone. Teladoc is the most well-known virtual care provider, but analysts predict that sales will be around $2 billion this year.

Teladoc should be able to acquire a larger share of its addressable market in three ways. One is to sign up new members, which the company regularly does thanks to several contracts with significant corporate clients. Another area where Teladoc is thriving is in increasing use. The business can also expand its product and service offerings. Teladoc is a fantastic example of this, with its Teladoc Primary 360 primary care service.

Outside of the United States, the company should have strong growth prospects. Virtual care's cost and convenience benefits aren't restricted to a single geographic zone. Teladoc, in my opinion, is simply scraping the surface of its potential. Cathie Wood, I believe, would agree.
