I would say that its going to be the best thing that you could do in your cryptocurrency invest to stick to Bitcoin and avoid junk tokens in the market, in the past Bullrun I had a lot of funds wasted investing on promising tokens in the market and thinking that it is already the best token that is going to make me rich but it wasn't, and it didn't really do anything, I just lose a huge amount of money that I could have just invested on Bitcoin instead. Still, it's not that bad to diversify your investment as long as you know your limits, I still have a few altcoins in the portfolio that one that I think have a good potential to make me good profit in the coming Bullrun, but my portfolio is still focused on Bitcoin, having a huge percentage in Bitcoin, probably only around 5% was altcoin just to have some fun and possible profit.

If you're going to take advantage of the Bitcoin halving probably its a good move to sell in the last pump when it reaches the all-time high since its probably the last time that we are going to see it, most of the time the market crash in the Bitcoin halving, so I'm really expected for a huge correction in the coming months, probably because of the market congestion and high fees why we delay the market crash but still expecting it, its either so sell on the last all-time high, then reinvest on the drop or hold until the next bull run.
