To avoid selling we need to strategize and plan our investment properly and not invest money we intend to use for other things and we should always set aside emergency funds to cater for unexpected expenses to avoid liquidating assets prematurely but most investors take it for granted and feel it’s not a necessity.
So, a investor will be successful only when our holding is long-term, so if we can hold for a long time through DCA with discipline and patience, we can definitely achieve big profits. And for this, we must make strategic decisions, and start holding with proper planning, and must keep emergency funds in the account, so that if we face unexpected expenses, we do not face any problem like stopping the holding.
Using the word cryptocurrency here might mislead other newbies going to put there money into shitcoins which they will definitely regret because you mentioned crypto currency or maybe you think it is only Bitcoin we have inside cryptocurrency no there are other unreliable coin in it such as shitcoins that's why it is not allowed in this thread.
