You will need to stay connected and read crypto news always, knowing when whales are buying
You will need to look for the coin to invest, it can be three, two or one or more, but do not let it be too many, but I will prefer to only choose like three at maximum and bitcoin will make up to 50%
Wait for the price to reach like $50000 or still decrease below such price
You will need to know how institutions are buying, any big buy, you can invest at that point.
For now, nobody knows if truely bitcoin price will still increase, it is constant that it will increase over long period of time but it could take longer than thought, and we do not know if the price will still dump below $50000, this is just a hard time period to invest. And, do not use the money you can not afford to lose, because the market is volatile.
