Before i can give any consideration on altcoins, i will first invest in bitcoin and make profits from it first, if i think I've got the momentum in taking the required risk from investing in any altcoin, then i will go ahead and make my investment at my own risk, not that all of these altcoins are that bad, but we need to exercise more care in dealing with them because one can make a loss beyond what he could afford to bear when we make investment in them.
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.
