Am not the one to endorse all altcoin, or point someone to the direction of trading or investing in one. But am the type of investor that does believe in shaking or shivering with situation.
Bitcoin is rising and thats good. Rumors can say the up coming bitcoin halving has something to do with it.
Many are now quick to sell off altcoin that they have been holding with so much promise.
This can be of bad consequences, I am the one to always invest in BTC if I have the found to get one, but I did not invest in bitcoin because of increasing price.
What you tend to loose selling of your coin
+ all your time of investment would become in vain: long term holder of altcoin should not without a thoughtful look sell off there coin
+ things might not go as you planned: the ball can go two ways, one it can go in your favour and two go against you.
I understand that investing in something more promising -bitcoin for example- is productive, but rather than, selling off just invest in it with available raw capital.
I guess investors shifted where the money is, so I'm sure that they are people who have been selling off their altcoins and move to bitcoin, we can't blame them. I have seen this kind of movements throughout my stay here in crypto. And it really makes sense to them though, I mean we all wanted to squeeze everything and make some good money isn't it? I myself did this, not regretting it since I made the right decision that time.
So I would advise though, if you are going to do this kind of strategy just be sure that you can stomach it, or shall I say be mentally tough and be prepared for the consequences. I'm not against the OP's advise or suggestion, what I'm saying is that you should try to work out a strategy that fits your needs, just saying.
