what we're all aiming for Bitcoin. We want to have more BTCs during the bull run and have it sold, not all of it at a better price.
Selling all isn't a wise decision because in the next years to come, the price of it will be higher.
Actually it seems you are the only one who is aiming to have some Bitcoin and sell it because nobody is using that kind of strategy here and our aim on Bitcoin is to keep accumulating till we get to our "Fuck you status" Just as JayJuanGee explained, And I would advise you to also do the same because with this kind of strategy you are talking about there is no different between you and traders, so you should no that accumulating and holding does not prevent your portfolio to increase as the Bitcoin price increases, so don't feel that your investment or rather portfolio will be stagnant, of course it will keep appreciating as you continue but that doesn't mean that you will be tempted to think about selling when you have not even have a sizeable amounts on your portfolio
The fees are only becoming a problem when the network is being spammed. But so far, there's no signs of it and hopefully they won't appear anytime soon.
I don't think there is a connection between network fees and accumulation of Bitcoin so network fee shouldn't be a problem that would hold you back from investing on Bitcoin because there is no fee associated during your Bitcoin accumulation, so all you just need is to invest on your weekly target, however I have not heard were any fees would prevent someone from there persistent accumulation of Bitcoin, so possibly you can clarify me on the connection the fees has against your Bitcoin accumulation.
