We all know that market is collapsed and reviving again and i don't want to miss this opportunity which coin or coins should i buy?
Simple, have big money? buy Bitcoin.
don't have big money then buy Ethereum.
make it simple, whatever you buy don't buy very small Fractions, always try to buy an entire coin or at least half a fraction of the entirety coin when the price is high like Bitcoin. Investing 200 usd in Bitcoin will give you a few profits, but the same investment if you put in Ethereum then it will give you partially higher profit.
But if you can effort to buy 1 BTC or 0.5 BTC then it will be the safest investment in your entire life.
