If you have enough money, I think choosing bitcoin is the right time. Soon the halving will occur, and it is very likely that the price of bitcoin will rise, and the price of altcoins will also follow the price increase. I think bitcoin can reach a new ATH, so when you have a lot of bitcoin at that time, I think the profits will be quite large. However, if you don't have too much money, I think choosing altcoins is the best way. But it all depends on how you see the current moment.
True. If we learned the history of previous halvings, Bitcoin price always increases significantly in the halving time. In April 20, halving is predicted to begin, we only has 1-2 days before the halving. So, it is likely the price of Bitcoin will start increasing again above $70k in the next few days. As long as Bitcoin is still below $65k, it is a good price for buying. If the price can return above $70k again, we take profits.
Well, choosing altcoins are not a bad idea. But choosing the right altcoins is easy, many of them are just pump-dump coins.
