As you know very well that there are so many coins which you can buy as well as hold it for certain period of time that it can give you some sort of good profit. I think that bitcoin is a good coin and it will give you exactly and obviously good sum of cash. Holding of bitcoin can be more fruitful as compared to hold any other coin. Select coin that will capable of giving you profit.
it is clear that there are many coins available and can be used as investments that are tailored to what you want and the funds you have, because there are too many alternatives available and if you are confused, you can use CMC/CGK for search and analysis that will be done first before deciding.
but I agree with you that the best option so far is to hold bitcoins, incidentally there is currently a correction. bitcoin can guarantee that for a long time it is certain that the price will be higher than when we bought it, because bitcoin has a very different character from other coins. that's the advantage that bitcoin has and is definitely very good for investment.
