Owning Bitcoin is always good, so you decided that correctly. Selling altcoins for it is okay, but if you want to play with higher gains or losses, then you should buy and sell altcoins. This is in most cases but with a lot of luck, you can also play at the roulette table something. On the other way, you will be very happy if you have bought a coin that has made a x10 and more. With bitcoin it will be less in the comparable time, but a more security not to lose everything, and with bitcoin you can be sure that it is denzentral.
Everyone is trying to mention that altcoins can give more profit, but not everyone says that not every altcoin is able to do this, there may be altcoins that will give even less profit than bitcoin and is it worth the risk and trying to find those very altcoins if you can just buy bitcoin.
It seems to me that the OP's decision to sell altcoins and buy bitcoin is a good decision. I would be interested to know the outcome of his decision in the bull market, whether it was correct, so that the OP writes us a summary of how the altcoins he sold were able to rise and how much profit bitcoin made, to find out if his decision was correct. Of course, this will not affect anything, but there is a certain interest in this, perhaps this would only confirm the confidence that this was the right decision.
