I suggest buying bitcoin while it's still on a dip or investing your money into much cheaper altcoin that is strong and has good fundementals and has new investments and developing new projects such as ETH and ltc. You could try to conduct your own research to where you wanna put all your money on just be sure that it's hype and has a lot of investors.
Personally, I suggest you should to buying Bitcoin as soon as possible. Now, ETF rumor is making the Bitcoin price dropped from $8300 to $7900. There's no reason to make U.S must careful to accept ETF funds for Bitcoin like now. U.S government know China, Korea and some countries in Asia and EU can take this advantage to release their idea, the legal framework and roadmap to apply cryptocurrency in the country's economy system to easy attractive the investor in the world. At that time, U.S will be the late country accept cryptocurrency and miss a lot of chance to grow its economic. So, maybe, the current price of Bitcoin is a trap.

My advise is to be prepared, do research, gain knowledge, learn to strategize, and be patient. Invest to a potential coin, do background check, the quality of the project, market cap, and its 24 hour price change. Invest an amount you can afford to lose, don't be afraid to explore new creative ideas. We learn from every experience, take it as an advantage for motivation and growth.
