$30k looks like the average low point of Bitcoin. Good time to buy the dip and HODL it for 10 or more years.
it is actually a good idea to hold for a very long time like 5 or 6 years, but 10 seems like a lot, he can make some good profit if things kept going well for crypto, it's the best option right now, i don't see bitcoin hitting some low price anytime soon, 25000$ can be the lowest bitcoin can get to.
Now the price of bitcoin has reached $ 46k and I'm sure tomorrow or the day after tomorrow the price will reach $50k, seeing this trend of course we will find it difficult to get a price of $25k, it's better to buy immediately before the price gets more expensive.
